What is formed when two or more elements combine chemically?

What is formed when two or more elements combine chemically?

What is formed when two or more elements combine chemically? When two or more elements combine to form a new substance, it is called a compound. A compound is made when atoms of two or more elements bond in a chemical reaction. Two hydrogen atoms and one oxygen atom bond to form a molecule of water (H2O).

When do two or more atoms join together to form a molecule?

Answer: A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.

What kind of bond forms between two atoms?

An ionic compound forms when electrons are transferred from one atom to another. When electrons are transferred, one atom becomes positively charged and the other takes on a negative charge. The bond that forms between the two atoms arises from the attraction of opposite charges. A covalent bond forms between two atoms that share electrons.

When does an ionic compound form what happens?

An ionic compound forms when electrons are transferred from one atom to another. When electrons are transferred, one atom becomes positively charged and the other takes on a negative charge.

What happens when two or more atoms are joined together?

Elements have properties that make them different from one another, but when two or more elements join chemically to form a compound, the compound has properties that are different from its constituents. Atoms in a compound can be joined ionically or covalently.

What makes a compound an element or compound?

A compound is a substance formed when two or more chemical elements are chemically bonded together. Two types of chemical bonds common in compounds are covalent bonds and ionic bonds. Each of more than one hundred substances that cannot be chemically inter converted or broken down into simpler substances and are primary constituents of matter.

What do you call two elements that are bonded to each other?

The name for two or more elements that are bonded to each other chemically is a compound. Compounds are not to be confused with isotopes or mixtures. Isotopes are alternate forms of an element’s…

How are atoms held together in a compound?

A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons.

Which is a compound that contains more than one element?

A compound is a molecule that is a substance made of two or more elements chemically combined in a set ratio. It contains more than one element, or type of atom. A compound is always a molecule, but a molecule isn’t always a compound.

When do two atoms chemically bond together they form a molecule?

When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3).
