Get Chapter 4 Atomic Structure Wordwise Answer Key

Atoms have three main parts: Protons, positively charged particles, make up part of the nucleus, which is in the center of the atom. Neutrons, uncharged particles, make up the other part of the nucleus. Electrons, negatively charged particles, orbit around the nucleus like the planets orbit the sun in our solar system.

An atom contains three basic particles namely protons, neutrons and electrons. The nucleus of the atom contains protons and neutrons where protons are positively charged and neutrons are neutral. The electrons are located at the outermost regions called the electron shell.

-Atoms are solid,homogenous, indestructible, and indivisible. -Different kinds of atoms have different shapes and sizes. -The different properties of matter are due to the shape, size, and movement of atoms. Dalton's Atomic Theory. -All matter is composed of extremely small principle called atoms.

The smallest particle of an element that retains the properties of that. element is called an atom.

Atomic structure is the structure of an atom that consists of a nucleus (the centre) and protons (positively charged) and neutrons (neutral). The electrons, which are negatively charged particles, circle around the nucleus's centre.

Primarily, the atomic structure of matter is made up of protons, electrons and neutrons. The protons and neutrons make up the nucleus of the atom, which is surrounded by the electrons belonging to the atom. The atomic number of an element describes the total number of protons in its nucleus.

An atom is made up of subatomic particles which are protons, neutrons, and electrons. They are electrically neutral due to the setup of them having equal numbers of electrons and protons, which balance each other out due to their negative and positive charges.
