GENERAL KNOWLEDGE

Detailed explanation-1: -Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.

Detailed explanation-2: -Atoms are made up of even smaller subatomic particles, three types of which are important: the proton, neutron, and electron. The number of positively-charged protons and non-charged (“neutral”) neutrons, gives mass to the atom, and the number of each in the nucleus of the atom determine the element.

Detailed explanation-3: -Atoms are the building blocks of matter.

Detailed explanation-4: -Matter is everything that occupies space and which has mass. Matter is made up of small particles called atoms. So these atoms are considered as building blocks of matter.

Detailed explanation-5: -Atoms are called the building block of matter. Atom: An atom is composed of positive, negative, and neutral subatomic particles. The particles that are present inside the nucleus are protons and neutrons while the negative particles (electrons) revolve around the nucleus in defined orbits.
