What is the group number of Y3?

The group number of Yttrium (Y) is 3.


Is ionization energy 5a group elements is greater than 6a grppoup elements?

Ionization energy generally increases across a period from left to right and decreases down a group. For the main group elements, Group 5A (nitrogen group) typically has higher ionization energies than Group 6A (chalcogens) due to the increased electron-electron repulsion in the more filled p-orbitals of Group 6A elements. Therefore, ionization energy for Group 5A elements is usually greater than that of Group 6A elements.


Which nonmetals are in group 5A?

Group 5A of the periodic table, also known as Group 15, includes the nonmetals nitrogen (N) and phosphorus (P). Additionally, this group contains metalloids such as arsenic (As) and antimony (Sb), but the primary nonmetals are nitrogen and phosphorus. These elements are known for their diverse chemical properties and are essential for biological processes.


What is the expected number of valence electrons for an atom of a group 5A element?

Group 5A elements, also known as group 15 in the periodic table, typically have five valence electrons. This is because they have five electrons in their outermost energy level. These elements include nitrogen, phosphorus, arsenic, antimony, and bismuth, and their ability to gain, lose, or share these electrons influences their chemical behavior.


Which of the following elements is NOT a member of group 6A oxygen selenium nitrogen sulfur?

Nitrogen is not a member of group 6A. It belongs to group 5A on the periodic table. The other elements - oxygen, selenium, and sulfur - belong to group 6A.
