COMPREHENSIVE EXAM 2026 QUESTIONS
AND SOLUTIONS GRADED A+
● nucleus. Answer: consists of protons and neutrons that are positively
charged, dense, heavier than electrons
● protons. Answer: positively charged element in the nucleus that binds
to a neutron
● electrons. Answer: negatively charged and orbit the nucleus
● Neutrons. Answer: uncharged atomic particles contained with the
nucleus
● true or false: the number of protons determines its identity. Answer:
True
● What is an Ion?. Answer: When an atom is not equal the atoms has a
positive or negative charge
● describe the three types of matter. Answer: solid: strong bonds
, liguid: weak bonds
gas: no bonds
● matter. Answer: substances that have mass and occupy space or
volume (solid liquid, gas)
● atomic number. Answer: the number of protons in the nucleus
determines this.
● atomic mass. Answer: total number of protons and neutrons in the
nucleus of the atoms
● charge of an atom. Answer: protons minus the number of electrons
finds what?
● binary compound. Answer: compounds that contain only two elements
● covalent compound. Answer: A covalent bond is formed between two
non-metals that have similar electronegativities. Neither atom is "strong"
enough to attract electrons from the other. For stabilization, they share
their electrons from outer molecular orbit with others.
● ionic compound. Answer: An ionic bond is formed between a metal
and a non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve
