Why is cell is the basic unit of life?
Cells make up the smallest level of a living organism such as yourself and other living things.
The cellular level of an organism is where the metabolic processes occur that keep the organism alive.
That is why the cell is called the fundamental unit of life..
Who said Atoms are the basic units of matter?
DaltonIn CO, the ratio is 1:1. In his theory of atomic structure and composition, Dalton presented the concept that all matter was composed of different combinations of atoms, which are the indivisible building blocks of matter.
What are the three basic units of matter?
An atom is made up of three particles: protons, neutrons and electrons.
What is the smallest unit of matter?
atomAn atom is the smallest unit of matter that retains all of the chemical properties of an element.
Is Salt a mixture?
A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements. When salt is added to water to make saltwater, it becomes a mixture.

What is the center of an atom called?
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
What is the basic unit of matter contained in common salt?
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
What is the scientific name for salt?
Sodium chlorideSodium chloride/IUPAC IDSalt (NaCl), sodium chloride, mineral substance of great importance to human and animal health, as well as to industry. The mineral form halite, or rock salt, is sometimes called common salt to distinguish it from a class of chemical compounds called salts.
