What is the combination of two or more of the same atoms called?

compound
A combination of two or more elements chemically combined is a compound .

What is a combination of more than one element?

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 combination of atoms called?

Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements.

What are two atoms of the same element called?

Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).

What happens when 2 atoms combine?

When two or more atoms chemically bond together, they form a molecule. In a covalent bond, electrons are shared between atoms. The bonds between the two hydrogen atoms and the oxygen atom in a molecule of water are covalent bonds. As its name implies, a metallic bond occurs between metallic substances.

Which combination is an element?

Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions.

Can an element be more than one of the same atom?

No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.

Are all atoms of one element the same?

No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.

Why atoms are combined together?

Atoms mainly combine to fill the outermost shell and they can combine with similar elements or different elements. Sometimes, they can achieve stability even after half-filled subshell. Electrons that are present in the outermost shell are known as valence electrons.

Are all atoms of the same element exactly the same?

What do you call the combination of the elements in the given sets to form a new set?

The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. The intersection of two sets contains only the elements that are in both sets.

What is it called when atoms combine to form a compound?

Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are generally not considered single molecules. Bold emphasis added. Unless by “combine” you mean “fuse,” the result is called a molecule, which is one form of a chemical compound. Cut from Wikipedia article Molecule:

What happens when two or more atoms of the same element?

If two or more atoms of the same element combine, they produce a molecule, for example, H2, O2, O3, etc. If, however, two (or more) atoms of different elements combine, they produce a compound, for example, NO, CO, FeS, NaCl, etc.

Which of the following compounds contains more than one atom?

Compounds that are composed of molecules are called molecular compoundsand contain more than one type of atom. Example -water (H2O), carbon mono-oxide (CO), carbon dioxide (CO2), ammonia (NH3), hydrogen chloride (HCl) etc.

What is the difference between an atom and a molecule?

Atoms & Molecules – Atoms are the smallest particle of an element, which may or may not have an independent existence but always take part in a chemical reaction. Molecules always exist independently and retain their physical and chemical properties.
