What is valence in chemistry?

In chemistry the valence or valency of an element is a measure of it's combining power with other atoms when it forms chemical compounds or molecules.

What is the D block?

The elements in group 1B-8B (also known as 3 through 12) are called the transition metals.

Why is the valency of helium zero?

The helium atom has only the 1s orbital in it's only shell, and it is completely filled with 2 electrons.

What is valency?

The valency of an element is the number of hydrogen atoms that can combine with or replace either (directly or indirectly) one atom of the element.

What is the valency of chloride?

There is no such element as chloride, it is the iconic form of the element chlorine. it has a valency of 1 and it's atomic number is 17, so it's electronic configuration is 2 8 7. Actually chloride is formed when chlorine gains an electron becomes stable, it is represented by Cl- and has 8 valence electrons.

How do you determine valence electrons?

To find valence electrons using a periodic table, first see if your atom is a transitional metal, which are the elements in the middle rectangle of the table.

What is special about valence electrons?

Valence electrons are the outermost electrons in an atom. Thus, they require less energy to remove than electrons at lower energy levels.
