The answer would be D because from my research it's the only one that didn't have a catalyst
The element which has the electronic configuration is CHLORINE.
The atomic number of chlorine is 17 and it has 7 valence electrons in its outermost shell. Because it needs only one more electrons to have a stable octet, it usually react with metals from group one of the periodic table who are normally willing to donate the single electrons in their outermost shells. The ground state electronic configuration of chlorine atom is 1S^2 2S^2 2P^6 3S^2 3P^5.
A because of the way it looks and how it works
Answer:
true
Explanation:
if u mix it can explode which is a chemical reaction
If it's properly adjusted ur head and nexk will stay in place for no further injuries.It helps so it don't move
