TEST BANK COMPLETE QUESTIONS AND
ANSWERS PRACTICE SOLUTION VERIFIED
◉ Matter. Answer: Anything that has volume and mass.
◉ Atom. Answer: The smallest particle of an element that retains the
properties of that element.
◉ Proton. Answer: A subatomic particle that has a positive charge and
is found in the nucleus of an atom.
◉ Neutron. Answer: A subatomic particle that has no charge and is
found in the nucleus of an atom.
◉ Electron. Answer: A subatomic particle that has a negative charge
and is found in an orbital surrounding the nucleus.
◉ Atomic Number. Answer: The number of protons in the nucleus of
an atom.
◉ The number of protons is equal to. Answer: the number of
electrons.
, ◉ Atomic Mass. Answer: the sum of protons and neutrons in an atom.
◉ Valence Electrons. Answer: The electrons in the outermost shell
(main energy level) of an atom; these are the electrons involved in
forming bonds.
◉ Periods. Answer: Horizontal rows on the periodic table. Determine
the orbitals surrounding the nucleus.
◉ Groups. Answer: Vertical columns on the periodic table. Can be
used to determine the number of valence electrons.
◉ Orbital of Atom. Answer: Three dimensional region around the
nucleus where the electrons are located.
◉ Rule of Octet. Answer: 1st shell has a maximum of 2 electrons;
every shell after has a maximum of 8.
◉ Ionic Bond. Answer: Formed when one or more electrons are
transferred between a non-metal atom and metal atom.
◉ Polar Covalent Bond. Answer: A covalent bond in which electrons
are shared unequally, resulting in a positive and negative pole.
◉ Non Polar Covalent Bond. Answer: A covalent bond in which
electrons are shared equally, resulting in a neutral charge.
