MODULE 006 Complete Solution 2023 Verified 100%
Matter correct answers Anything with mass and volume
Element correct answers A substance that cannot be broken down
Compound correct answers A substance made up of multiple elements in fixed ratios
Atom correct answers The smallest unit of a element that retains all the chemical properties of the
element.
Proton correct answers A subatomic particle found in the atomic nucleus. It has a positive charge.
Neutron correct answers A subatomic particle found in the atomic nucleus. It has a neutral charge.
Electron correct answers A subatomic particle that orbits the nucleus in an electron cloud. It has a
negative charge.
Dalton correct answers A unit of measurement used for atoms, which is equal to an amu. It is roughly
the mass of a proton.
Atomic number correct answers The number of protons an atom has, which is unique to a type of
element.
Atomic Mass correct answers Sum of neutron and proton masses in an atom. It is roughly equal to the
number of nuclear particles in an atom.
Isotope correct answers A version of an atom with the same number of protons but a different number
of neutrons. They act the same way in chemical reactions, but some are unstable and decay into
different elements through radioactive decay.
Energy Levels correct answers Areas in which an electron can be, which correspond with the amount of
potential energy an electron can have. Electrons can only exist in these discrete levels. Atoms absorb
and release energy by changing the levels in which the electrons are.
Valence electrons correct answers Electrons in the outermost shell of an atom. They are the electrons
typically responsible for chemical reactions.
Covalent bond correct answers An atomic bond that can result when two atoms share electrons, which
contributes to filling both their valence shells. Single (two electrons shared), double (four electrons
shared) and triple (six electrons shared) can occur.
Electronegativity correct answers The attractiveness of an atom to electrons. In some molecules, it
causes areas that are electronegative to attract electrons and become positive, and some areas to
become negative.
