What is it called when two molecules join together?

What is it called when two molecules join together?

In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.

Is a molecule composed of two atoms?

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 do you call a particle that is composed of 2 or more joined atoms and combined with other molecules to form macromolecules?

Compounds are made up of two or more elements combined in definite quantities and in definite proportions by chemical bonds. Substances are pure forms of matter that cannot be separated or purified further by physical means; include compounds and elements.

What is a join between atoms called?

When two electrons are shared between two neighbouring atoms, they are said to be joined by a covalent bond. When covalent bonds form between atoms, the resulting entity is called a molecule with a fixed characteristic geometry.

What is a molecule answer?

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 and one atom of oxygen react with each other and form one molecule of water.

What kind of molecule is composed of two or more elements?

chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements.

Can a molecule have one atom?

Monoatomic is when a molecule of an element contains only one atom. For example, Helium – He and Potassium – K. A molecule is diatomic when it contains two atoms. For Example, Nitrogen gas –N2.

What is it called when 2 smaller atoms join together to form a larger one?

Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission.

When atoms combine and bond together they form a particle called a?

When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element.

What connects two atoms together?

A covalent bond happens when atoms share an electron between them. The other kind of bond is called ionic, and it happens when one atom gives an electron to another atom. These bonds are held together with electric forces.

What is a true molecule?

A true molecule has a beginning and an end – held together with covalent bonds. Water is a great example of just 3 atoms (H, O, and H) held together with 2 bonds (two identical H‑O bonds).

What is molecule quizlet?

Molecule. A neutral group of atoms held together by covalent bonds. Chemical reaction. The process by which one or more substances undergo change to produce one or more different substances.

What is a molecule example?

Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element. Fig.
