No, it has the wrong number of valence electrons.
The correct number is: ☐
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* |
Yes.
No, it has the wrong number of valence electrons.
The correct number is:
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* |
If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many
times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0".
