Know the Answer?

Kaitlyn Sherman · Answer 1

Answer: The correct answer is Option A.

Explanation:

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons present in an atom.

Mass number = Number of neutrons + Number of protons.

We are given:

Atomic number = 38

Mass number = 88

Number of neutrons = Mass number - Atomic number = 88 - 38 = 50

Hence, the correct answer is Option A.

Answer: The correct answer is Option A.

Explanation:

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons present in an atom.

Mass number = Number of neutrons + Number of protons.

We are given:

Atomic number = 38

Mass number = 88

Number of neutrons = Mass number - Atomic number = 88 - 38 = 50

Hence, the correct answer is Option A.
