What do chlorine and fluorine have in common?
What Makes Them Similar? When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. Fluorine is the most reactive and combines with most elements from around the periodic table.
What group is fluorine and chlorine in?
Group 7A
Is fluorine similar to chlorine?
halogens: Group 17 (or VII) in the periodic table consisting of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They share similar chemical properties.
How the electron configurations of fluorine F and chlorine Cl are similar?
Referring only to the periodic table, tell how the electron configurations of fluorine and chlorine are similar. F and Cl will have the same number of electrons in the outermost shell, but Cl will have more electrons in more shells.
Do Period 5 elements all have six 5p electrons?
Period 5 Elements Have An Inner Electron Configuration Of [Kr]. Period 5 Elements All Have Six 5p Electrons.
What happens when the first 2 electrons are removed from calcium?
Calcium loses 2 electrons when it becomes an ion. Since calcium lost two electrons, it has 20 protons, but only 18 electrons. This makes calcium a positive ion with a charge of 2+. Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons.
Does oxygen lose or gain electrons?
Elements in Groups 15,16 and 17, find it easier to gain electrons than lose them. For example, oxygen atoms gain two electrons to form O2- ions. These have the same electron configuration as the noble gas neon. Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure.
Which best explains why ionization energy tends to decrease?
The ionization energy decreases because the full s orbital shields the electron entering the p orbital. Which best explains why ionization energy tends to decrease from the top to the bottom of a group? Electrons get farther from the nucleus.
Which is a correct set of values of M?
Answer: The correct set of values of m for one of the subshells is -1,0,1. Explanation: The “Principal quantum number” (n) represents the number of shells (levels) that an atom has where the electrons has the higher probability to be find.
Which model is useful in showing the reactivity of potassium?
Answer : Option D) Both the models because each shows an electron in the outermost shell. Explanation : It is clearly seen that the model 1 and model 2 has the electronic configuration which is same for potassium. The reactivity in potassium is seen because of the one electron present in the outermost valence shell.
What set of numbers gives the correct possible values of L for N 2?
Answer Expert Verified For n=2, (n-1) is equal to 1, so the range is 0 and 1.
Which is the electron configuration for lithium quizlet?
1s2
Which is the correct electron configuration for arsenic?
[Ar] 3d¹⁰ 4s² 4p³
What is the electron configuration of the lithium ion?
[He] 2s1
What is the full electron configuration for Zn?
[Ar] 3d¹⁰ 4s²
What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
iron
Why does Zn have a 2+ charge?
Zinc has an electron configuration of [Ar] 3d10 4s2. On the fourth (and outermost) electron shell, Zinc has only two electrons before coming to a closed n=3 shell. Losing all the electrons on the fourth shell would mean Zn lost two negative charges, making it the ion Zn+2.
Which species is Zn2+ or Zn?
(b) Which species, Zn or Zn2+, has the greater ionization energy? Justify your answer. Zn2+ has the greater ionization energy. The electron being removed from Zn2+ experiences a larger effective nuclear charge than the electron being removed from Zn because Zn2+ has two fewer electrons shielding the nucleus.
Is Zn paramagnetic or diamagnetic?
Because there are no unpaired electrons, Zn atoms are diamagnetic.
Does Cu2+ react with Zn?
The Cu2+ is called the oxidizing agent because it causes the Zn(s) to be oxidized to Zn2+.
Why is zinc not a transition metal?
Those metals which have partially filled d-orbitals are transition metals. Zinc has completely filled d-orbital and should thus not be a metal for transition.
Why is manganese a transition metal and zinc not?
Transition elements are defined as elements that form at least one ion that contains partially filled d orbitals. The electronic configuration for a zinc atom is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10. As none of the d orbitals are partially, zinc cannot be classified as an transition element.
Why zinc is not a noble gas?
A valence subshell is one which can react to form a bond. So the definition of valence orbitals doesn’t depend on their quantum numbers, but on the energy required to fill them. That’s why zinc is not a noble gas – the 4p orbitals count as valence (reactive) orbitals for zinc even while the 4d don’t.
Do all elements have a noble gas configuration?
They are helium, neon, argon, krypton, xenon, and radon. A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons….Noble Gas Configuration.

Is chlorine a noble gas?
The elements that are found in the last column of the periodic table are an important group of elements that are called the noble gases. They are helium, neon, argon, krypton, xenon, and radon….Noble Gas Configurations.

Which gas does not exist in air?
– Therefore Radium is not a noble gas and it is not present in the atmosphere. So, the correct answer is “Option B”. Note: Radium is not available in nature because it is prepared from a radioactive decay of other radioactive elements.
Why are there no ideal gases?
At relatively low pressures, gas molecules have practically no attraction for one another because they are (on average) so far apart, and they behave almost like particles of an ideal gas. At higher pressures, however, the force of attraction is also no longer insignificant.
Which noble gas is more soluble in water?
Xenon
