Question

An atom has 14 protons, 17 neutrons, and 18 electrons. What is its mass number, atomic number, and charge?

Answer 1

The mass number is 31, the atomic number is 14, and the charge is 4+.

Step-by-step explanation:

The mass number is the total number of protons and neutrons in an atom's nucleus. In this case, the mass number would be 14 (protons) + 17 (neutrons) = 31.

The atomic number is the number of protons in the nucleus, which in this case is 14.

The charge of an atom is determined by the difference between the number of protons (positive charge) and the number of electrons (negative charge). In this case, 18 (electrons) - 14 (protons) = 4, so the charge would be 4+.

Answer 2

Mass number = 31

Atomic Number = 14

Charge = -4

Step-by-step explanation:

14 protons

17 neutrons

18 electrons

Mass number = ?

Mass number = protons + neutrons.

`Mass\:number = 14+17\\\\Mass \:number = 31`

Atomic number = ?

The number of protons = atomic number.

Atomic number = 14

Charge = ?

The charge of an element = number of protons minus the number of electrons.

`Charge=14 -18\\\\Charge = -4`
