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.


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....


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 can you find group no?

The number of valence electrons tell us the group number of that element.


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.


How many valence electrons in any element in a group?

Same as 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.


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.


What determines the group an element is placed in?

The number of electrons in the outermost orbital.


Atoms of element that are in the same group have the same number of?

valence electrons
