Want this question answered?
6 x 2 = 12. 4 are part of a double covalent bond; the other 8 form lone/nonbonding pairs.
eight, thus the valence shell is full, which is why they do not normally bond
This number is different for each anion.
2
the outermost electrons of an atom. these are called valence electrons. atoms are also grouped in the periodic table based on their valence electrons. to complete a full outermost shell there must be 8 electrons. hydrogen has 1 valence electron. and oxygen has 7. they are able to bond together because of how many valence electrons they have.
26 Count every sigma bond (13), double it to get number of valence electrons (26).

it has 4 valence electrons
6 total valence electrons. go apex!

Carbon atoms do not gain electrons to form a covalent bond. Carbon atoms form four covalent bonds by sharing its four valence electrons with the valence electrons of other atoms. These can be single bonds, in which one pair of electrons is shared; double bonds, in which two pairs of electrons are shared; or triple bonds, in which three electrons are shared; or a combination of these.
Four electrons (2 pairs) are shared in a double covalent bond.
A total of 6 electrons.
This number is different for each cation.
