Answer 1

Answer:

The correct option is G) Mercury has 51 more electrons than copper.

Explanation:

Atomic number can be described as the number of protons in an atom. As the number of protons is equal to the number of electrons for a neutral atom, hence atomic number also depicts the number of electrons.

The atomic number of mercury is 80. This means that an atom of mercury has 80 electrons.

Th atomic number of copper of copper is 29 which means that copper has 29 electrons.

80 - 29= 51

Hence, mercury has 51 more electrons than copper.
