Answer: Magnets have a force which is known as no contact force. This force tries to attract the metallic objects near it, which makes it move.
Explanation:
<span>The electronic configuration of cobalt is :1s2 2s2 2p6 3s2 3p6 3d7 4s2 </span>
The reactivity of a metal is determined by these things.
Firstly, the number of electrons in the outer shell; the fewer the number of electrons in the outer shell, the more reactive the metal.
The number of electron shells also affects reactivity, the more electron shells there are, the more reactive the metal.
Answer is True. They can in one lifetime by either humans or natural
