Two atoms each have 14 neutrons. The first has 13 protons and 13 electrons and the second has 14 protons and 14 electrons. Are these atoms isotopes of the same chemical element? Why?

Explanation:

Nope both atoms aren't isotopes of same chemical elements.. In isotopes both atom should have same number of protons or atomic number with different mass number, but here it's 13 and 14 protons so different atomic number

answer; natural resources;

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
