Question

In its outermost shell,a metal cannot have

Answer 1

Answer:

more than 2 electrons

Explanation:

this is derived by 2n^2

n is number of the orbit

2×1^2

=2

Answer 2

Answer:

As we know that metals have the tendency to lose electron and therefore acquires a positive charge.

So elements having valance electrons 1, 2 and 3 will loose their electrons and will thus acquire a positive charge, which means that the elements are METALS.

And also the elements having valance electrons 4, 5, 6 and 7 will acquire a negative charge by gaining electrons, which inturn symbolize that these elements are NON METALS.
