Draw a Lewis structure for ClO4- in which the central Cl atom obeys the octet rule, and answer the following questions based on your drawing. a. The number of lone pairs on the central Cl atom is:
b. The central Cl atom forms single bonds.
c. The central Cl atom forms double bonds.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

it would be a gas formation

it is the most commonly accepted one

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
