Answer 1

Answer:

protium, deuterium,

tritium

Answer 2

Carbon and hydrogen have 3 isotopes.

Explanation:

A nucleus of an element contains both protons and neutrons. Isotopes of an element can be defined as forms of the same element that just have different numbers of neutrons in the nucleus. Isotopes can also be defined as elements that have the same atomic number but the different mass numbers and that occupy the same position in the periodic table.

Elements that have three isotopes are:

1. Hydrogen: with hydrogen, deuterium, and tritium.

Hydrogen: have no neutrons.

Deuterium: have 1 neutron.

Tritium: have 2 neutrons.

2. Carbon: ¹²C, ¹³C, ¹⁴C

¹² C = has 6 neutrons

¹³C = has 7 neutrons

¹⁴C = has 8 neutrons
