Carbon has 4 valence electrons so to gain a noble gas electron configuration, which has 8 valence electrons and is the most electrically stable, carbon needs 4 more electrons.
Answer:different elements have different number of electrons and shells/orbits thatswhy it have different atomic mass and size.
Explanation:
Hey there!
Oxygen needs two bonds to have a valence orbital of s²p⁶.
In a hexanal molecule, oxygen has a double bond with one carbon atom.
A double bond is when two pairs of electrons are being shared.
So your answer is b. 2.
Hope this helps!
an ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures (as in the upper atmosphere and in fluorescent lamps) or at very high temperatures (as in stars and nuclear fusion reactors).
