Question

The diagram represents an atom 'X'. Answer the following.

How many electrons will 'X' lose or gain to become $X^{+1}$?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer: (A)

$X$ will loss 1 electron to become $X^{+1}$ .
The metal loses one or more electrons while the nonmetal gains one or more. The number of electrons lost depends on the position of the metal in the periodic table. Group 1 elements lose 1 electron, group 2 elements lose 2 electrons. A positive charge results when an electron is lost because the number of protons then exceeds the number of electrons.
