How many electrons does cl lose or gain
WebA Ca atom has two valence electrons, while a Cl atom has seven electrons. A Cl atom needs only one more to complete its octet, while Ca atoms have two electrons to lose. Thus we need two Cl atoms to accept the two electrons from one Ca atom. The transfer process looks like this: The oppositely charged ions attract each other to make CaCl 2. WebThere are 7 valence electrons for chlorine, and it would have 1 bond and three pairs of dots. Same for bromine (Br) and iodine (I). Octet Rule for the Noble Gasses The noble gasses are noble. They don’t bond. They are already born with 8 electrons, generally, so they already obey the octet rule without bonding.
