How many valence electrons are there in group 2?
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).
How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
How many electrons are in the valence shells of group 1?
Group 1 elements have one valence electrons.
How many valence electrons are in group 1a elements?
The 1a elements have 1 valence electron.
How many valence electrons do group 4A elements have and why?
Group 4A electrons have 4 valence electrons, because it contains 4 valence electrons on the 3rd principle energy.
How many valence electrons do the elements is group two have?

How many valence electrons do group 7a elements have?
Elements in group 7A have 7 valence electrons. Elements in group 1A have one valence electron, elements in group 2A have 2 valence electrons, etc. Noble gases have a full outer shell of 8 valence electrons.There are 7 valence electrons in group 7A.
