Structure of Matter Notes

Elements and Compounds

What are compounds?

The substances which, if divided, give away two or more elements are called compounds.

Atoms and Molecules

What are atoms?

Atoms are the smallest particles of elements that contain the characteristics of the elements.

What is a molecule?

When two or more atoms remain connected with each other in a chemical bond, it is known as a molecule.

What are element molecules?

When more than one atom of specific element bonds to each other, they produce that element's molecule.

Symbols of Elements

What is a symbol?

The abbreviated form of the English or Latin name of an element is called its symbol.

Write the Latin name of Mercury?

The Latin name of Mercury is Hydrargyrum.

The Particles Inside an Atom

What particles are there inside an atom?

There are different particles including electrons, protons, and neutrons in the atoms.

What is an electron?

Electron is one of the permanent element particles of an atom containing a negative charge.

What is a proton?

Proton is one of the stable particles of an atom containing a positive charge.

What is a neutron?

A neutron is one of the stable particles of an atom containing no charge.
