No, "ne2" is not an ionic compound. "Ne2" would represent a molecule of two neon atoms bonded together covalently, since neon is a noble gas and does not typically form ionic bonds.
A molecule of Ne2 does not exist because neon is a noble gas with a full valence shell, making it stable and unlikely to form covalent bonds with another neon atom. Additionally, the lack of available orbitals for bonding in neon atoms prevents them from forming a stable molecule.
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
Calcium normally has 20 electrons. Because it has a plus 2 charge, it must have two less electrons. Therefore, the calcium ion has 18 electrons.
Argon (Ar) has 8 valence electrons. When it forms a 2+ ion (Ar2+), it loses 2 electrons, leaving it with 6 valence electrons.
No, "ne2" is not an ionic compound. "Ne2" would represent a molecule of two neon atoms bonded together covalently, since neon is a noble gas and does not typically form ionic bonds.
The number of electrons is 10.
It has 4 d electrons.
19 Protons and 20 electrons
11 protons and 10 electrons
This cation has 24 electrons.
The H+ ion has no electrons.

Pb2+ has lost two electrons, so it has 82 - 2 = 80 electrons.

CArbon has an atomic number of 6. There are therefore only 2 electrons in C4+
Mn has 25 protons.
