Contains 15 Electrons And 19 Neutrons

Which element 3

1) It has 22 protons and 21 neutrons.

2) It has 15 electrons and 19 neutrons.

3) 10 neutron oxygen atoms

4) A chrome atom numbered m 54.

22 protons = years. 22 + 21 = m is number 43, so isotope anion43 if necessary.

15 electrons means 15 protons, which is Psprus. 15 + 19 = m number 34, i.e. psprus34.

Oxygen contains 8 protons. 8 protons + 10 neutrons = m number 18, so oxygen is 18.

The latter will give you what you need, whether it's chromium (24 protons) or chromium 54.
