Atomic structure True and false Questions and Answers 100% Solved

Atomic structure True and false

False: Nucleus - answer The central core of the atom is called the HUB.

True - answer The chart showing the classifications of elements according to their
properties and increasing atomic numbers is called the PERIODIC TABLE

False: Neutron - answer The mass of an ELECTRON is about equal to the mass of
proton.

False: Family or Groups - answer Elements arranged in vertical columns in the periodic
table are called PERIODS.

False: CL - answer The symbol for chlorine is C.

False: 8 - answer The maximum number of electrons in the second energy level of an
atom is 4.

False: Neutrons - answerTwo isotopes of Carbon are carbon-12 and carbon-14. These
isotopes differ from one another by two ELECTRONS.

True - answerNONMETALS are poor conductors of heat and electricity.

False: nonmetals - answerSeven electrons in the outermost energy level is
characteristic of a METAL

True - answerQuarks can be produced by bombarding PROTONS with protons

False: Atomic Number - answerThe number of protons in an atom is called the ATOMIC
MASS.

True - answerThe sum of the number of protons and the number of neutrons in an atom
is the MASS NUMBER

False: Mass number - answerThe weighted average of the mass numbers of all the
isotopes that occur in nature for a particular element is the AVERAGE ATOMIC
NUMBER.

True - answerA very stable electrons arrangement in the outer energy level is
characteristic of NOBLE GASES

False: Metals - answerElements having three or fewer electrons in the outer energy
level are classified as NONMETALS
