An atom.
However it should be noted that generally the valence electrons in an atom take part in a chemical reaction.
A compound is a substance formed by the chemical bonding of two or more elements in specific proportions. A molecule is the smallest portion of a compound.
Elements can be broken down into smaller pieces: a compounds smallest particle is a molecule
elements..because.....two elements form a compound
The smallest whole bit of matter for elements is an atom, for compounds is a molecule, and for mixtures is a particle.
A molecule is the smallest unit of a chemical substance that retains its chemical properties, consisting of two or more atoms held together by chemical bonds. A compound is a substance composed of two or more different elements chemically bonded together in fixed proportions. In essence, all compounds are molecules, but not all molecules are compounds.
both are pure substances, but atoms represent the smallest bits of elements. compounds are chemically combined atoms, molecules represent the smallest bits of compounds. atoms cannot be broken down into simpler substances, compounds can be broken down into atoms.
Well, they can form molecules. Molecules join together to form elements. Elements join together to form compounds.
Atoms are the smallest particle possible of an element. Compounds are made up of molecules which have more than one elemental type of atom; compounds are chemical mixtures of different elements.
An atom. Anything smaller is an atomic particle from which all elements are made.An atom is the smallest particle of an element that has properties of that element.An atom is the smallest unit of an element that retains the properties of that element.
The smallest particles of elements that enter into chemical reactions are known as atoms.
A chemical compound is a pure chemical substance that consists of two or more different chemical elements which can be separated into simpler substances by a chemical reaction. A molecule is the smallest unit of a compound.
Molecules are the smallest units of compounds, which are made up of two or more different elements chemically bonded together. Pure substances can be either elements or compounds. All three are related in that they have specific chemical compositions and properties that are unique to their structure.
The chemical formula of a compound shows the number of atoms of each element in the smallest unit of the compound. The smallest unit is a molecule for covalently bonded compounds and the minimum number of each of the right kinds of atoms to achieve electro-neutrality for ionically bonded compounds.
An element is a substance made up of atoms with the same number of protons, while a compound is a substance made up of two or more different elements chemically bonded together. Elements cannot be broken down further by chemical means, while compounds can be broken down into their constituent elements.
A compound is a substance formed by the chemical bonding of two or more elements in specific proportions. A molecule is the smallest portion of a compound.
Atoms are the smallest units of an element. Molecules are the smallest unit of a compound.
Molecular compounds are formed by sharing electrons between atoms, leading to the formation of covalent bonds. They do not conduct electricity in their solid form because they do not contain free ions. Molecular compounds typically have lower melting and boiling points compared to ionic compounds.
