Answer:
The last question is not complete. This is the possible question " How many atom of oxygen and hydrogen is in water molecule"?
The answers are:
1) 1 proton
2) 8 Neutrons
3) 1 Electrons
4) 2 electrons
5) Ionic bond
6) 6 Electrons
7) Inner or S orbit
8) 2 atoms of hydrogen and one atom of oxygen
Step-by-step explanation:
Atomic number is the number of proton in the nucleus of an atom.
The proton number is equal to the number of electron of an atom.
The formula: mass number = proton number + neutron number is used to calculate either the proton number or the neutron number of an atom.
The K shell contains 2 electrons in it's shell. The L shell contains 8 electron and the M shell also contains 8. Oxygen has 6 electrons in it's outermost shell while hydrogen has only one.
Ionic bond involves the sharing of electrons between two atoms bearing a negative and a positive charge. It exist between hydrogen and oxygen atom.
