Question

2 A student is given two diagrams, a neutral copper

atom and a neutral mercury atom. Which statement
best describes the difference in the number of
electrons for these two atoms?
F Copper has 29 less electrons than mercury.
G Mercury has 51 more electrons than copper.
H Copper has 51 more electrons than mercury.
J Mercury has 29 less electrons than copper.​

Answer 1

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

Step-by-step 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.
