element

Are compounds made of only one atom?

By definition a compound is composed of two or more different elements chemically bonded, which is same as saying more than one kind of atom. Examples of molecules that are not compounds but contain more than one atom, each of which is the same kind of atom.

What consists of only one substance?

A pure substance is something that occurs in nature. An element is made up of one type of atom only and cannot be split further. A compound has the combined properties of the elements from which it is made. Atoms show the macro properties of an element.

Which is a substance that is made up of only one type of atom quizlet?

An element is a pure substance consisting of only one type of atom.

What type of substance is always made up of a single type of atom quizlet?

A pure substance containing only one kind of atom. An element is always uniform all the way through (homogeneous). An element cannot be separated into simpler materials (except during nuclear reactions).

What type of substance is always made up of a single type of atom mixture element molecule compound?

All matter is composed of atoms. If a substance is made of only a single type of atom, then the substance is an element. Conveniently, all of the known elements are listed on the periodic table of elements. Substances like gold, silver, oxygen, carbon, hydrogen, and helium are all elements.

What does it mean if the sample is made up of only one substance or more than one substances?

mixture A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. A mixture refers to the physical combination of two or more substances in which the identities of the individual substances are retained.

Can you have a molecule with only one type of atom yes or no?

Molecules are made up of atoms. Each element on the periodic table of elements is made up of one single type of atom. … Different types of atoms can form together to make a molecule. Two or more of the same type of atom can also be bonded to make a molecule.

Can elements contain more than one type of atom?

Atoms of the same element with different numbers of neutrons are called isotopes. … If a substance contains more than one type of atom, it is a compound or a mixture. The smallest particle of a compound is a molecule. 118 different chemical elements are known to modern chemistry.

Which of the following substance is made up of only two element?

A pure substance, basically composed of two or more elements and chemically combined in a fixed proportion is called a compound. Therefore, water is a compound. It has two elements, hydrogen and oxygen, combined in a fixed ratio.

Are atoms always combined in some way?

Compounds: • A pure substance containing two or more kinds of_atoms • The atoms are chemically combined in some way. Often times (but not always) they come together to form groups of atoms called molecules. … Mixtures can be separated into their components by chemical or physical means.

Which type of substance is always made up of two or more different types of atoms joined by chemical bonds?

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.

Is homogeneous exhibits only one phase?

By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.
