Summary Introduction

To compare:

The term atom, electron, neutron, nucleus, proton by defining them.

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.

Summary Introduction

To fill:

The given blanks with the given vocabulary terms.

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 chemical bonding between two or more atom.

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.
