What is vertical and horizontal column?
Horizontal columns in a periodic table-When we move from left to right or right to left, columns in a periodic table are horizontal columns. These are also known as periods. Vertical columns in a periodic table-When we move from Top to Bottom or Bottom to Top, columns in a periodic table are vertical columns.
Which element has the smallest radius?
Helium
Which element in period three has the largest atomic radius?
Sodium
Which atom is larger aluminum or phosphorus?
the order of these elements in periodic table is Aluminum, silicon, phosphorus and sulfur. As we know that atomic size decreases from left to right . So, the the element with highest atomic radius is aluminum and then silicon followed by phosphorus and sulfur.
What is the atomic radius of phosphorus?
195 pm
Why is atomic radius of chlorine smaller than phosphorus?
Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine’s valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to …
Which is bigger phosphorus or chlorine?
Normally, phosphorous has a larger atomic radius compared to sulfur and sulfur has a larger atomic radius compared to chlorine. Even though you are adding electrons to the atoms, the atomic radius of phosphorus is still larger than sulfur and same thing with chlorine.
Which is smaller magnesium or phosphorus?
Answer. Magnesium has a larger atomic radius due to a smaller effective nuclear charge. B Phosphorus has a larger atomic radius due to a larger effective nuclear charge.
Is Sodium more metallic than phosphorus?
How do the atomic radius and metallic properties of sodium compare to the atomic radius and metallic properties of phosphorus? A) Sodium has a larger atomic radius and is more metallic.
Which element is the most metallic?
The most metallic element is francium. However, francium is a man-made element, except for one isotope, and all isotopes are so radioactive they almost instantly decay into another element. The natural element with the highest metallic character is cesium, which is found directly above francium on the periodic table.
Which element has the ground state electron configuration Kr?

What is the correct electron configuration for V+?
1 Expert Answer In shorthand, the electron configuration for V is [Ar]4s23d3 .
What is the electron structure of V2+?
Vanadium’s electron configuration is 1s22s22p63s23p64s23d3. Vanadium is a d-block transition metal, therefore we remove the two valence electrons from the 4s subshell to form vanadium(II), giving us 1s22s22p63s23p63d3. Alternatively, this can be written using the symbol [Ar] to represent the noble gas core; [Ar]3d3.
Which molecule will have a double bond?
Double bonds are common for period 2 elements carbon, nitrogen, and oxygen, and less common with elements of higher periods.
Which elements can be Hypervalent?
Phosphorus pentachloride (PCl5), sulfur hexafluoride (SF6), chlorine trifluoride (ClF3), and the triiodide ion (I3−) are examples of hypervalent molecules.
Can any atom be Hypervalent?
When atoms contain more than eight electrons in their valence shell, they are said to be hypervalent. Hypervalency allows atoms with n≥3 to break the octet rule by having more than eight electrons. This also means they can have five or more bonds; something that is nearly unheard of for atoms with n≤2.
Is PF5 a Hypervalent?
Your textbook explains that stable hypervalent molecules can be formed when the central atom is in the n = 3 row or higher because d-orbitals are available to form the extra bonds. Thus, PF5 has net four covalent bonds and one ionic bond.
Is IF7 Hypervalent?
Answer. Answer: Phosphorus pentachloride (PCl5), sulfur hexafluoride (SF6), chlorine trifluoride (ClF3), IF7 are the examples of hypervalent molecules. it is a molecule that contains one or more main group elements bearing more than 8 electrons in their valence shell.
Is pcl3 a Hypovalent?
Hypervalent is a molecule that contains elements having more than 8 electrons in the valence shell. For example, PCl5, SF6, etc. Hypovalent are the molecules that have less than 8 electrons in their valence shell.
Which bonds are longer in IF7?
IF7 has 7 bond pairs making it pentagonal bipyramidal which has the axial bonds longer than the equatorial ones.
Is IF7 an electrophile?
(V)- .. CCl3: In this compound the carbon atom has a total of eight electrons, so it is a complete molecule. In this, the carbon atoms have six electrons, so it can accommodate two electrons, therefore it will be an electrophile. (VIII)- ˙CF3: This compound is a free radical, so it will be an electrophile.
Is pcl3 a Electrophile?
PCl3 as an electrophile.
Is pcl5 is an electrophile?
Electrophiles is one of the chemical species that either donate or accept electrons to form a new chemical bond. The answer is “Yes”, pcl5 is an electrophile.
Why pcl3 is a Electrophile?
PCl3 as an electrophile These compounds do not usually contain the chlorine atoms found in PCl3. PCl3 reacts rapidly and exothermically with water to form phosphorous acid, H3PO3 and HCl.
Is alcl3 an electrophile?
An electrophile is deficient of electrons in nature. Therefore, according to the octet rule aluminium can accept two more electrons to have a total of eight electrons in the octet. Therefore, AlCl3 is an electrophile.
