Question

An element has an atomic number of 76. The number of protons and electrons in a neutral atom of the element are ____.
a.
152 protons and 76 electrons
c.
38 protons and 38 electrons
b.
76 protons and 0 electrons
d.
76 protons and 76 electrons

Answer 1

Google the definition od atomic number... and you should know that the charge of an atom needs to be balanced so the number of protons is the same as the number of electrons... The answer is D

Answer 2

The correct answer is D. 76 protons and 76 electrons.

Explanation

The atomic number is a term used in physics and chemistry to refer to the structure of the atoms of each element. This number indicates the total number of protons (positive charges) in the nucleus of an atom. It is usually represented by the letter Z. Usually, the atoms in their natural state are neutral, this means that their number of electrons (negative charge) and protons are equal, for example, an iron atom (Fe), has an atomic number of 26, It has 26 electrons and 26 protons. Therefore, a neutral atom of the element with an atomic number of 76, has 76 protons and 76 neutrons. So, the correct answer is D. 76 protons and 76 electrons.
