Answer:
b
Explanation:
b/c proton + neutron=mass number and
mass number - proton= neutron
Answer:
According to molecular orbital theory, chemical bond occurs as electrons are able to reduce their energy by entering the resulting molecular orbitals.
Chemical bonds are not located among atoms, they are distributed all over the molecule.
Uses test methods to solve the equation of Schrodinger.
You can never do better than nature, however strong your assumption is. Calculations of minimum energy must be done by software.
Answer:
the first one I believe is right but I could be wrong.
Lithium is a good reducing agent because it is electropositive [it rapidly gains electrons]
fluorine is good oxidizing agent electronegative [it loses electrons fastly]
