False, Carbon usually forms four covalent bonds.
The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)

V=D/T
V is speed
D is distance
T is time
V=D/T
31.67 m/s = 1361.81 m / T
31.67/31.67=1361.81/31.67
T=43 seconds
Hope this helps
