Answers
Answer:
please mark me as branliest
Explanation:
orbits:An orbit is a regular, repeating path that one object in space takes around another one.
atomicity:the number of atoms in the molecules of an element.
symbols:Chemical symbols are abbreviations used in chemistry for chemical elements, functional groups and chemical compounds
dalton atomic theory:Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. ... The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.
atomic number:the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
mass number : the total number of protons and neutrons are called mass number
a)
An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them.
b) Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms.
c) A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. ... Symbols take the form of words, sounds, gestures, ideas, or visual images and are used to convey other ideas and beliefs.
d) Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. ... The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.
e) the number of positive charges or protons in the nucleus of an atom of a given element, and therefore also the number of electrons normally surrounding the nucleus.
f) the integer nearest in value to the atomic weight of an atom and equal to the number of nucleons in the nucleus of the atom. Symbol: A.
