How many electrons occupy p orbitals?
6 electrons
How many electrons are there in the p orbitals of the last shell of chlorine atomic number 17?
This means, that the number of electrons present in an chlorine atom is 17. Where k, l, ,m are the shells/orbits/ energy levels of an chlorine atom. Valence electrons are the number of electrons present in the outermost shell of an atom. Now, the last shell of chlorine atom has 7 electrons in it.
How many p orbitals are occupied in a Ne atom?
three p orbitals
How many electrons occupy p orbitals in an arsenic atom?
Arsenic, As , is located in period 4, group 15 of the periodic table and has an atomic number equal to 33. As you can see, the outermost shell is the fourth shell, n=4 . This shell contains a total of 5 electrons, 2 in the 4s-orbital and 3 in the 4p-orbitals.
Which orbitals have the highest energy?
The energy of an electron versus its orbital Within a given principal energy level, electrons in p orbitals are always more energetic than those in s orbitals, those in d orbitals are always more energetic than those in p orbitals, and electrons in f orbitals are always more energetic than those in d ortitals.
What is the highest energy orbital occupied by electrons in the ground state of a chlorine atom?
third energy level
What is the highest occupied energy level for chlorine?
seven
What is the lowest energy level?
At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a 2p3. Each of these orbitals can hold 2 electrons, so a total of 8 electrons can be found at this level of energy.
How many electrons can a chlorine atom have?
Once one shell is full, the next electron that is added has to move to the next shell. So… for the element of CHLORINE, you already know that the atomic number tells you the number of electrons. That means there are 17 electrons in a chlorine atom.
Does it make sense that a chlorine atom would accept two electrons?
Atoms want to fill their valence shells. They’re most stable (and thus most happy) with a full outer shell. Sodium, chlorine, and oxygen atoms all want outer shells to have 8 electrons. It’s other two options are to accept 7 electrons, or just give up 1.
How many chlorine atoms can bond to a single atom of carbon?
Each chlorine atom has seven valence electrons in the third energy level and requires one more electron to form an electron core with an argon electron configuration. Each chlorine atom contributes one electron to the bonded pair shared by the two atoms….Covalent Bonds.
| Atom | Valence |
|---|---|
| Carbon | 4 |
What is the charge of Br?

How many VE does BR have?
7 valence electrons
Why does pb have a 2+ charge?
It’s valence shell only has 2 electrons out of the 8 it wants, and the d shell has 5 orbitals with only one filled with 2 electrons. It wants to get rid of that 4s2. To do so, it loses two electrons, giving it its +2 charge.
Which ion has a charge of 2?
A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+. The symbol for the ion is Mg2+, and it is called a magnesium ion.
Which is more stable Pb2+ and Pb4+?
Moreover, in case of transition elements of the same group, higher oxidation state is more stable for heavier elements. In non-transition elements of p-block, lower oxidation state is more stable due to inert pair effect e.g., Pb2+ is more stable than Pb4+.
Why is Sn4+ more stable than Sn2+?
At lead, the +2 oxidation state is the more stable, although +4 compounds do exist. a) The Sn2+ ions convert to Sn4+ ions because the tin(IV) oxidation state is more stable than tin(II). This means the loss of two more electrons from the tin(II) ions, and these have to be given to something else, which gains them.
Which is more stable sn2 or sn4?
The electronic configuration of Sn is 5s2 5p4. It can lose four electrons to achieve full filled configuration. Therefore, Sn. Due to this stable electronic configuration, Sn4+ is more stable than Sn2+.
Which of the following is most stable Pb2+ ge2+?
Owing to this,only the valence orbitals participate in bonding and thus this is known as inert pair effect. -Thus in the given question we can infer that Pb2+ is the most stable.
What is inert pair effect in P block elements?
The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. As a result, the inert pair of ns electrons remains more tightly held by the nucleus and hence participates less in bond formation.
What is poor shielding effect?
Poor shielding means poor screening of nuclear charge. In other words, the nuclear charge is not effectively screened by electrons in question. The shielding effect of different orbitals is as follows: s orbital’s > p orbital’s> d orbital’s> f orbital’s.
What is inert pair effect and its consequences?
The inert pair effect is the reluctance of s-electrons to take part in bond formation. A chemical consequence is the occurrence of oxidation states which are two units less than the group oxidation.
What is shielding effect and inert pair effect?
The key difference between inert pair effect and shielding effect is that inert pair effect is the ability of a pair of electrons in the outermost electron shell to remain unchanged in post-transition metal compounds, whereas shielding effect refers to the reduction of the attraction force between electrons and atomic …
Is screening effect and inert pair effect?
The inert pair effect explains why common ions of Pb are Pb4+ and Pb2+, and not just Pb4+ as we might expect from the octet rule. Screening effect : The shielding effect describes the balance between the pull of electrons on valence electrons and the repulsion forces from inner electrons.
What shows inert pair effect?
Clearly, the element which is most likely to show inert pair effect is Pb. Option (D) is the correct answer.
How does inert pair effect affect oxidation state?
Inert pair effect is more as we go down the group. As a result the stability of highest oxidation state decreases and the stability of lowest oxidation state increases.
What is the oxidation state of sulfur?
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
Which oxidation state is more stable?
Some examples of the trends in oxidation states However, down the group, there are more examples of +2 oxidation states, such as SnCl2, PbO, and Pb2+. Tin’s +4 state of is still more stable than its +2 state, but for lead and heavier elements, the +2 state is the more stable; it dominates the chemistry of lead.
Why oxidation state decreases down the group?
The tendency to exhibit -3 oxidation state decreases as we move down the group due to an increase in the size of the atom and the metallic character. Due to the inert pair effect, the stability of +5 state decreases and +3 state increases as we move down the group in the periodic table.
