How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
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 makes element becomes active?
An element is chemically active till it does not attain an inert gas configuration.
How many valence electrons does an element in 5A contain?
5 valence electrons.
Why is so much emphasis placed on valence electrons?
The valence electrons of an element are mainly what determine an element's properties.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
How many valence electrons will make an element chemically stable?
The number depends on what will fill the outer shell. It can be 2 or 8.

What makes element becomes active?
An element is chemically active till it does not attain an inert gas configuration.
What are Valence elcetrons?
Valence electrons are the electrons on the outermost energy shell of an element.
