The number of valence electrons in groups 3 through 7 is the same as the group number, and for group 12 the number of valence electrons is 2. For groups 8 through 11, the number of valence electrons must be determined individually from individual electronic configurations.

What is one property that is specific to each of the groups on the periodic table?

The number of valence electrons is unique to each group. For example, group 1 has 1 valence electron, and group 3 has 3 valence electrons, and group 7 has 7 valence electrons. This is unique for each group as no other group has that same number of valence electrons.


How many valence electrons does a group 1A metal atom have?

they all have one valence electron.


What is the number of valence electrons for the elements in group 1?

Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.


How do you determine the number of valence electrons if you know the group no of elements?

valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1

Which pair of atoms will have the same valence-shell electron configuration Se and Te Sr and Cs N and O H and He?

Se and Te will have the same valence-shell electron configuration as they are both in the same group (group 16) and have 6 valence electrons. Sr and Cs will have different valence-shell electron configurations as Sr is in group 2 with 2 valence electrons and Cs is in group 1 with 1 valence electron. N and O will have different valence-shell electron configurations as N has 5 valence electrons while O has 6. H and He will have different valence-shell electron configurations as H has 1 valence electron and He has 2.


How would you find valence electrons in a periodic table?

To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number 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.
