Well, that's kinda like asking "apple plus apple?". When you put different types of atoms together, it makes a molecule.
nass number is the number of neutrons plus protons in the nucleus of an atom
The Mg atom has more electron than the Mg+2 ion.
No
To form a 1+ ion a lithium atom must lose 1 electron. The same goes for any other atom.
H+, plus one
The lithium atom lose an electron.
nass number is the number of neutrons plus protons in the nucleus of an atom
No, an anion is the atom plus extra electrons which give that atom a negative charge. The anion is thus, always bigger than the original atom.
the mass number is number of protons in an atom, plus the number of neutrons.
The Mg atom has more electron than the Mg+2 ion.
No
This is an ionic bond and electrons are donated from the K atom to the Iodine atom
minus plus minus
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
HCl is formed.
the mass number of an atom is the number of protons in an atom, plus the number of neutrons.
Na^+ represents a sodium atom that has lost ONE ELECTRON.
