.............​

Answer 1

Answer:

Explanation:

It is well known to us that an atom consists of protons, neutrons, and electrons. The central mass of an atom is made up of protons and neutrons and electrons revolve in orbitals. The number and arrangement of protons, neutrons and electrons in an atom determine the physical, chemical and electrical properties of an element. The numbers and arrangements of protons, neutrons and electrons in an atom are collectively called structure of an atom of the element. The structure is alternatively called atomic structure.

Answer 2

Every atom of metallic conductor has one or more outermost electrons which are very weakly bound to the nucleus. These are called free electrons.

• Electrons are subatomic particle and hold a magnitude of charge -1.

• Free electrons reside in the valence shell of an atom, they are also known as valance shell electrons, and are very loosely bound with the nucleus of the atom.
• Since, they have weaker interaction with the nucleus, they can move independently within a material and that is why they are called as free electrons.
• The force of attraction of the nucleus does not act on the free electron. The flow of free electrons in a material is called an electric current. The moving free electrons will pass electric current from one point to other in a material.
