atoms are the basis of?
314084
Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

Atoms. An atom is the smallest unit of a pure substance or element that can exist and still retain the properties of the original substance or element. Key concepts: common substances, such as air, water, wood and cloth are mixtures of materials and can be chemically or physically broken down into simpler substances.

Cells are the basis of life—the basic structural unit of living things. Molecules such as water and amino acids are not alive but cells are! ... You will also focus on the cell membrane, which is the structure that surrounds the cell and separates its internal environment from the external environment.

Atoms. Atoms are everywhere! They make up everything around us and are the building blocks of life. They are made up of three different particles - protons, neutrons, and electrons.

In chemistry, a base is a substance that can either accept hydrogen ions (protons) or, more generally, donate a pair of valence electrons; it can be thought of as the chemical opposite of an acid. Strong bases are commonly, though not exclusively, formed from the hydroxides of alkali metals and alkaline earth metals.

The nuclei of all atoms contain subatomic particles called protons . The nuclei of most atoms also contain neutrons . The masses of subatomic particles are very tiny.

In mathematics, a set B of elements (vectors) in a vector space V is called a basis, if every element of V may be written in a unique way as a (finite) linear combination of elements of B. The coefficients of this linear combination are referred to as components or coordinates on B of the vector.

Protons, neutrons and electrons The modern view of the atom is of a nucleus containing protons and neutrons with smaller electrons orbiting outside the nucleus.

Atoms are the fundamental unit of matter and composed of three subatomic particle: protons, neutrons and electrons. ... The fundamental unit of matter is the atom, meaning this is the smallest particle of matter that has the properties of that substance.

But, atoms themselves contain many subatomic particles, the three most important of which are protons, neutrons, and electrons. These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number.

Explanation: All elements, and compounds, all matter in point of fact, are composed of atoms. In a compound, there are 2 or more different types of atoms present that are chemically bound. In an element, there is only the one type of atom.

Well, the basic building blocks that make up matter are called atoms. Sometimes two or more atoms bond, or stick together, and form a molecule. ... Atoms consist of three particles: negatively charged electrons, positively charged protons and neutrons, which have a neutral charge.

The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. Atoms fit together with other atoms to make up matter.

Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.

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.

The atoms of all the elements have electrons, protons, and neutrons. They all have atomic masses. They all share similar properties with the other elements. They can also become any of the four states of matter.
