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
the answer is yes
it has kinetic energy
reason
an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
