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

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.

A. What is the mass number of the particle emitted from the nucleus

Alexus [3.1K]

Answer: For a. Mass number for the particle is 0.

For b. The charge on the particle is -1.

For c. Another name for $\beta$ - particle is electron.

Explanation:

Beta- minus decay is the decay process in which beta-particle is emitted. The mass number of the nuclei remains same and the mass number of the particle is 0. The charge on the particle is -1 and the emitted particle is also called as electron.
