Question

if a lithium has 3 protons, 3 neutrons, and 3 elestrons, an isotope of this atom would have how many protons, neutrons, and electrons

Answer 1

An isotope of this atom would still have 3 protons and 3 electrons. It is the number of neutrons that changes. For that u would have to have the mass number of the atom since p + n = ma, therefore ma - 3 = n

Answer 2

An isotope of Lithium atom would still have 3 protons and 3 electrons.

What is an isotope?

When two elements have same atomic number or the number of neutrons present in the nucleus but different masses.

Given the lithium atom with protons, 3 neutrons, and 3 electrons. Its isotope will have same number of neutrons.

The mass number will change due to the change in neutrons.

Thus, an isotope of Lithium atom would still have 3 protons and 3 electrons.
