Answer 2

Answer:

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. The nucleus is surrounded by mostly empty space, except for very tiny particles called electrons that orbit the nucleus. Recently, scientists have discovered that protons and neutrons are made of smaller particles known as quarks
