This would be an ionic bond.
The electronegativity of Hydrogen is about 2.2 and the electronegativity of Fluorine is about 4.0. The difference is 1.8 which is greater than 1.7, the minimum difference for an ionic bond.
Added:
Or it is (at least) a very polar-covalent bond. Figures 1.7 or 1.8 are in the 'discussion' range
There are two, one from H and one from F being shared between them.
It will differ depending on the specific molecule the H-H bond is present in, but on average to break apart one mole of covalently bonded H-H gas you will require 432kJ.
One electron

there are 5 bonding electrons. It depends on the number of valence electrons.
Phosphorous has a total of 15 electrons, and of those, 3 of them are valence shell, or bonding electrons. So, 12 electrons are core electrons, and are non-bonding.
Two bonding electrons are in the molecule of H2O (light water)
The electrons out of ionic bonds and covalent bonds are called as non bonding electrons. Valence electrons are the bonding electrons of carbon.

Ten nonbonding electrons and 14 bonding electrons are in acetyl chloride.

Two valence electrons
There are three bonding pairs of electrons in BF3. There are 0 nonbinding pairs, but BF3 can accept two more electrons to give it a complete octet
8 bonding electrons

ow many valence electrons in methyl fluoride/
Electrons involved in bonding between atoms are valence electrons.
Ionic bonding depends on the number of electrons. The number of neutrons is not relevant.
