what is an atom?

Answer 1

An atom is the smallest, indivisible, part of an element which still maintains all of the physical and chemical properties of that element.

It consists of a central core (called the nucleus) which contains protons and neutrons, and which is encircled by orbiting 'electrons'. Some of these electrons are capable of interacting with other electrons from other atoms to form 'chemical bonds' by which more complex 'molecules' of different substances may be created.

Physics & Chemistry
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10-8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
This unit regarded as a source of nuclear energy. See Table at subatomic particle

Answer 3

Atoms are the basic units of elements and are smallest possible elemental form to maintain elemental qualities.

Answer 4

Atom : is the smallest particle still characterizing a chemical element.
an atom consists of : electrons,protons,and neutrons.

Answer 5

an atom is the smallest component of an element having the chemical properties of the element. for more info go on to the bbc bitesize revision website. it has all the answers. :-D

Answer 6

The smallest possible piece of an element without taking it apart/changing its characteristics
