(8)Ionic bond

(2)Chemical bond

(3)Compound

(6)Hydrogen bond

(9)Organic compound

(1)Atom

(5)Element

(10)Periodic table

Answer 1

(4) Covalent bond - the bond formed by the sharing of a pair of electrons by two atoms.

(7) Inorganic compound - any substance in which two or more chemical elements (typically not carbon) are mixed in precise quantities.

(8) Ionic bond - a chemical bond that forms when two ions with opposite charges come together. When one atom gives up one or more electrons to another, an ionic bond is formed.

(2) Chemical bond - a mutual attraction between two atoms resulting from a redistribution of their outer electrons.

(3) Compound - a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds.

(6) Hydrogen bond - a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

(9) Organic compound - a type chemical compounds where one or more than one carbon covalently bonded with each other and with other atom like nitrogen, oxygen, or halogen.

(1) Atom - the smallest particle of an element that can exist either alone or in combination an atom of hydrogen.

(5) Element - a substance that cannot be broken down chemically into simpler substances. An element is made up of atoms with the same atomic number, which means that each atom has the same number of protons in its nucleus as the other atoms in the element.

(10) Periodic table - a table of chemical elements arranged in atomic number order, commonly in rows, with elements having comparable atomic structures (and thus chemical characteristics) appearing in vertical columns.
