An atom is the smallest unit of matter that retains all of the chemical properties of an element. Elements, such as helium, depicted here, are made up of atoms. Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.

What is an atom short answer?
An atom is the smallest component of an element and the building blocks of all matter, characterized by sharing of the chemical properties of the element and a nucleus with neutrons, protons, and electrons.
What is an atom in a cell?
An atom is a chemical unit. A cell is made by molecules that are made by atoms. Therefore atoms are smaller than cells. Cells are made of molecules like proteins, carbohydrates, lipids and nucleic acid, whereas atoms are made of electrons, protons and neutrons.
What is an example of an atom in biology?
An atom is the smallest component of an element that retains all of the chemical properties of that element. For example, one hydrogen atom has all of the properties of the element hydrogen, such as it exists as a gas at room temperature, and it bonds with oxygen to create a water molecule.
What is atom definition with example?
An atom is the defining structure of an element, which cannot be broken by any chemical means. A typical atom consists of a nucleus of positively-charged protons and electrically neutral neutrons with negatively-charged electrons orbiting this nucleus.
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 an atom Class 10?
Atoms are the fundamental building block of a matter that retains its all chemical properties. As we can see, most of the mass of an atom is concentrated in its nucleus. The mass of an electron is only 1/1836 the mass of the nucleus of the lightest atom, that of hydrogen.
What do atoms do?
An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules.
How do atoms form cells?
They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs. These combinations continue until entire multicellular organisms are formed.
What is a molecule vs atom?
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.
What are 4 examples of atoms?
Here are some examples of atoms:
- Neon (Ne)
- Hydrogen (H)
- Argon (Ar)
- Iron (Fe)
- Calcium (Ca)
- Deuterium, an isotope of hydrogen that has one proton and one neutron.
- Plutonium (Pu)
- F–, a fluorine anion.
What are atoms give two examples?
An atom is any particle of matter at its most basic level which contains at least one proton. Here are some examples of the atoms: hydrogen (H) neon (Ne).
Is oxygen an atom?
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.
What is atom in physical science?
atom, 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 atom in science class 8?
An atom is defined as the structural and functional unit of a matter. The term “atom” comes from the Greek word which means indivisible, because atoms are the smallest things in the universe and could not be divided. atoms are made up of three subatomic particles like protons, neutrons and electrons.
What are 5 types of atoms?
Different Kinds of Atoms
- Description. Atoms are made of tiny particles called protons, neutrons and electrons.
- Stable. Most atoms are stable.
- Isotopes. Every atom is a chemical element, like hydrogen, iron or chlorine.
- Radioactive. Some atoms have too many neutrons in the nucleus, which makes them unstable.
