Answer:

$]\huge\pink{\mathfrak{Answer:-}}$

Explanation:

• Atoms are the basic units of matter and the defining structure of elements.

• The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

• We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.

• Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form.

• Quarks came together to form protons and neutrons, and these particles combined into nuclei.

• The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight).

• N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole.
