It is an ionic bond.
Yes, the ionic bond is strong to held the two atoms together such as NaCl .
NaCl is an example. It is an ionic compound.
An ionic bond do hold the atoms of NaCl together.
The formula unit -NaCl - (not a molecule) contain two atoms.
nuclei because a chemical bond is a mutual attraction between the NUCLEI and valence ELECTRONS of different atoms that binds the atoms together
Any atoms from Group 1 or 2 form ionic bonds. e.g NaCl MgI2 KBr CaCO3 BaSO4
Yes, NaCl is weak ionic bond.
NaCl
The formula unit of sodium chloride (NaCl) has two atoms.
The formula unit of NaCl (sodium chloride) contain 2 atoms.
A metal as Alkali metals and a non metal as Halogens may form an ionic bond as Na and Cl (NaCl), K and F (KF).
When atoms bond but do not share electrons this is known as an ionic bod. Here electrons are donated from one of the atoms to another in order to ensure that both atoms have a full outer shell. E.g. MgO or NaCl
