Question

The table below gives the numbers of protons, electrons, and neutrons in four atoms. Atom Number of protons Number of electrons Number of neutrons 1 39 39 52 2 40 40 50 3 39 39 54 4 40 40 51 Based on the information that is given, which atom in the table has the highest mass? 1 2 3 4

Answer 1

Atom 3 or C. Took the Exam and passed. Good luck and have a good day!

Step-by-step explanation:

Answer 2

Answer : Atom 3 in the table has the highest mass.

Explanation : Given table,

Atoms 1 2 3 4

Number of protons 39 40 39 40

Number of electrons 39 40 39 40

Number of neutrons 52 50 54 51

Atomic mass is calculated by the addition of Number of protons and Number of neutrons are present in an element.

Atomic mass = Number of protons + Number of neutrons

The Atomic mass of Atom 1 = 39 + 52 = 91

The Atomic mass of Atom 2 = 40 + 50 = 90

The Atomic mass of Atom 3 = 39 + 54 = 93

The Atomic mass of Atom 4 = 40 + 51 = 91

Therefore, Atom 3 has the highest atomic mass.
