H2 + O2 → H2O

Is this chemical reaction balanced? If not, how would you correct it?

2H2 + O2 → 2H2O

500

These radioactive elements have a different number of neutrons, which causes the mass number to change as a result. Cobalt-60 is an example.

What are isotopes?

500

Give me the correct formula for Magnesium Chloride.

Remember valence electrons and octet rule.

MgCl2

Mg wants to GIVE its two valence electrons. Cl can only take ONE each because it has 7 and can only hold 8. One Mg electron will go to one Cl atom and the other electron will go to a second Cl atom.
