Final answer:

Cobalt (Co) has 27 protons, and a cobalt ion with a +2 charge (Co2+) has 25 electrons.

Step-by-step explanation:

The question asks about the number of electrons and protons in a cobalt ion with a +2 charge (Co2+). Cobalt (Co) has an atomic number of 27, which means it has 27 protons. The ion Co2+ has lost 2 electrons compared to a neutral cobalt atom. Therefore, Co2+ has 27 protons and 25 electrons. The positive charge of the protons is partially cancelled out by the negative charge of the electrons, and the 2+ charge indicates that there are two more protons than electrons.

Answer:

20 protons 18 electrons i think

Step-by-step explanation:

an atom with an ionic charge of +2 has two more protons than electrons. The element calcium, for example, has atomic number 20 so the atom has 20 protons. The calcium ion with a positive +2 charge has two more protons than electrons.
