what is the difference between atoms elements and compounds?

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. ... A compound is a substance made from two or more different elements that have been chemically joined.

An atom is the smallest amount you can have of an element whereas a molecule is the smallest amount you can have of a compound.

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.

A radical is an atom, ion, or molecule that has unpaired electrons. An element is a substance made up of the same type of atoms. A compound is a combination of two or more elements. Based off these definitions, we know that radicals, elements, and compounds biggest difference is there size.

Elements are the purest form of a chemical substance and are composed of only one type of atom. In other words, all of the atoms in an element will have the same number of protons. ... A mixture is a combination of two or more different chemical compounds or elemental substances.
805621
A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element.

What is the difference between native elements and compounds? Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. ... A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.

All the atoms of an element have the same properties (assuming they are the same isotope). Some examples are iron, magnesium, gold, etc. Compounds are composed of two or more elements in a fixed ratio.

Atoms are the thing that make up molecules and compounds. Molecules contain two or more atoms and are held together by covalent bonds, whereas compounds are held together by ionic bonds. ... The atoms within a compound also must be different from eachother, whereas a molecule can consist of only one element.
415959
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. ... Elements that compose the compound are chemically combined. Elements contain only one type of atom.

A compound is a pure substance that is composed of elements chemically bonded in definite proportions. A compound can be broken down into simpler substances only by chemical reactions, such as electrolysis. A solution is a homogeneous mixture, meaning that it is the same throughout.
986715
All compounds are molecules, but not all molecules are compounds (if they happen to have atoms of the same element). Diatomic molecules are molecules composed of only two atoms of either the same or different elements.

Compounds, and mixtures Elements are key ingredients in compounds and mixtures. The similarities between compounds and mixtures are that they are both made up of two or more elements and that they could both be separated and then mixed with different elements to make a new mixture and compound.
1198085
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. ... Each chemical substance has a specific chemical composition, so these chemical substances have their own chemical formula.
957176
A compound is a pure substance composed of two or more different atoms chemically bonded to one another. That means that it can not be separated into its constituents by mechanical or physical means and only can be destroyed by chemical means. ... The constituent elements in a compound are in a fixed proportion by weight.

Molecules are made up of two or more elements. Compounds are made up of two or more DIFFERENT elements. In determining if you have molecules or compounds remember that a compound is also a molecule.

Compounds are made of two or more atoms of different elements, such as water (H2O) and methane (CH4). Atoms are not drawn to scale. Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom.
