How can you determine the number of valence electrons for an element on the periodic table?

To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.

What is the formula for valency?

The valency of an element is determined by the number of electrons it gains, loses, or shares to achieve a stable electron configuration. It is typically the same as the number of electrons an element needs to gain or lose to achieve a full outer shell (octet). For example, elements in Group 1 have a valency of +1 because they lose one electron to achieve stability, while elements in Group 17 have a valency of -1 because they gain one electron to achieve stability.

What is the expected number of valence electrons for a group 3 A element?

The expected number of valence electrons for a group 3A element is 3. These elements have three valence electrons because they are located in group 3A of the periodic table, which corresponds to the third column from the left.

How many valence electrons in arsenide ion?

Arsenide ion has 3 valence electrons. Arsenic, the element from which arsenide ion is derived, is in group 15 of the periodic table, so it has 5 valence electrons. When it forms an ion with a charge of -3, it gains 3 electrons to achieve a full octet.
