Atoms are known to form charges due to their ability to gain and lose electrons in reactions. As a result, atoms
become ions that are positively or negatively charged depending on the loss or gain of electrons. Which of the
following atoms has a charge of +2 given the number of electrons?
O A. O: 10 electrons
OB. N: 10 electrons
O C. Fe: 24 electrons
OD. Cl: 18 electrons

Answer:

C. Fe: 24 electrons

Explanation:

From the analogy given, the atom with a charge of +2 is Fe having 24 electrons.

To calculate the charges on an atom;

     Number of charges = Number of protons - Number of electrons.

   O: 10 electrons: 8 protons = 8 - 10 = -2

   N: 10 electrons; 7 protons = 7 - 10 = -3

   Cl: 18 electrons; 17 protons = 17 - 18 = -1

So;

    Fe: 24 electrons and 26 protons = 26 -24  = +2

Therefore, the solution is Fe
