What is atom explain?

An atom is the basic building block of chemistry. It is the smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element.

What is difference between atoms and molecules?

What is an atom and molecule? The ‘simple building blocks of matter’ are known as atoms. The properties of the chemical element are the smallest constituent unit of substance. Molecules are made up of one or more atoms connected by covalent (chemical) bonds.

What is molecule answer?

Molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.

What is an atom Class 9 short answer?

Answer: The definition of an atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons.

What is a molecule example?

A Look at Molecules In simple terms, a molecule is an atom that forms a chemical bond with another atom. This could be another atom of itself in the case of the oxygen gas humans breathe (O2), or it could be bonding with another atom as in when two hydrogen atoms chemically bond with oxygen to make water (H2O).

What is molecules class 9th?

A group of two or more than two atoms of the same or different elements that are chemically bonded together is called a molecule. For example: Two atoms of hydrogen (H2) and one atom of oxygen (O2) react with each other and form one molecule of water.

What are atoms Class 9?

The smallest tiny particles of matter which can’t be divided further is called atom, i.e., an atom is the smallest building block of matter. For example: Sodium (Na), Hydrogen (H), Oxygen (O), etc.

What is an atom Class 10?

Atoms are the fundamental building block of a matter that retains its all chemical properties. Everything in this universe is made up of matter.

What do you mean by molecules?

(MAH-leh-kyool) The smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.

What is a molecule year 7?

Molecules are made when two or more atoms chemically bond together. Atoms from different elements can combine. When the atoms are from different elements, the molecule can also be called a compound.
