How many valence elactrons do all the elements in neon's family have?
8 valence electrons are there in in neon's family .They are stable in nature.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Do all the elements in the second column of thde periodic table have a valence number of 2?
No, not all elements in the second column of the periodic table have a valence number of 2. Elements in group 2 have a valence number of 2, but elements in period 3 or below can have different valence numbers due to the presence of d or f orbitals which can contribute to their valence electron count.

What does the group number of A elements in the AB numbering system tell about valence electrons?
The group number of A elements in the AB numbering system indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on. Valence electrons are important because they determine the chemical properties and reactivity of an element.
