Explanation of Solution
Atoms are defined as the smallest particles of the elements and the building block of the matter. Atoms have a smaller particle called neutrons, protons, and electrons.
Nucleus is the central part of the atom and it consist of neutron and protons.
Proton is a positively charged particle of an atom.
Neutron is a particle of present in the nucleus, which does not have an electric charge.
Electron is a negatively charged particles. It is located outside of the nucleus.

Answer to Problem 1NV
The blanks can be filled as follows:
Blank | Term |
1 | Element |
2 | Isotope |
3 | Compound |
4 | Covalent bond |
5 | Molecule |
6 | Ion |
7 | Ionic bond |
8 | Van der Wall force |
Explanation of Solution
An element is a Substance that cannot be broken down in other substance. An isotope it is a substance that have different atomic mass due to the difference in number of neutrons. A compound is a substance that is formed by
A bond in which electrons are shared for holding elements together is known as covalent bond. A molecule is a substance formed by covalent bonding. An ion is an atom that loses or gain an electron and carries a charge.
When two oppositely charged electrons are attracted toward each other and forms a bon then this bond is termed as ionic bond. The attraction between charged region of molecules takes place, this type of force is called van der Wall force.
