Answer:
When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules.
Explanation:
Answer:
Protons= 11
neutrons= 12
electrons = 10
Explanantion:
Look for Na on periodic table
Atomic Number = 11
Atomic Mass = 23 (round it to be an integer)
Number of protons = Atomic number = 11
Number of neutrons = Atomic mass - atomic number = 23-11 =12
Number of electrons = 11 - e = ´+1 , electrons = 10
