If by group A u mean Group 1, that would be one. Except for the transition metals, the # of valence electrons is equal to the one's place of the group #, except for helium because it can only have 2 and it is in the 8 group, but that is the group that has the most it can have.

What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
How do you use te periodic table to identify the number of electrons available for bonding?
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
What does the group number help tell you in columns?
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
What is the number of valence electrons for carbon?
4 electrons
What do you notice about the number of valence electrons as you move down or up a group or column in the Periodic Table?
The number of Valence electrons of an element is the same number as the element's group number. E.g. Hydrogen is in Group 1. Therefore it has 1 valence electron. Another e.g. Oxygen is in Group 6. Therefore it has 6 valence electrons.
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.

How are the number of valence electrons related to the group number?
In s and p blocks the number of valence electrons in an element is the same number of the group which that element belongs to. Hope this helps....

How many valence electrons are there in phosphuros?
The number of valence electrons in any element can be found from the element's group number on the periodic table. Phosphorus has a group number of 5 (15 in some periodic tables, in which case the valence is the group number minus ten). Thus, phosphorus has 5 valence electrons.
How can you find group no?
The number of valence electrons tell us the group number of that element.
How many valence electrons in any element in a group?
Same as the group number.
Number of valence electrons found in an atom of a group A element is equal to what?
group #
What can you use to ditermine the number of valence electrons of an element in the s block and p block?
For the group 1 and 2 elements, the group number is the number of valence electrons. For groups 13 - 18, subtract 10 from the group number to get the number of valence electrons.
The number of electrons in atoms determine in element's propertices?
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
