GENERAL ORGANIC AND BIOLOGICAL
CHEMISTRY TEST 51 ACTUAL TEST PAPER
QUESTIONS AND SOLUTIONS GRADED A+
◉ metals.
Answer: found on the far left side of the periodic table
◉ metalloids.
Answer: the diagonal strip of elements on the right side of the
periodic table
◉ nonmetals.
Answer: on the far right of the periodic table
◉ daltons atomic theory.
Answer: *atoms are neither created nor destroyed
*all matter is composed of atoms
*atoms of two or more different elements are called compounds
◉ subatomic particles.
Answer: Protons (1+) mass of about 1
,Neutrons (0) mass of about 1
Electrons (1-) mass of nearly 0
◉ atomic number.
Answer: is how many protons one element contains
◉ mass number.
Answer: the weight of each individual element
◉ isotopes.
Answer: are elements that have the same number of protons but a
different number of neutrons
◉ atomic mass.
Answer: is the weighted average of the masses of the naturally
occurring isotopes for that number isotopes for that number
◉ electron energy levels.
Answer: each electron has a specific energy level, usually those with
lower energy levels have the nucleus closer to them.
◉ electron arrangement.
, Answer: gives the number of electrons in each energy level the order
of electrons possible in each shell.
◉ valence eletrons.
Answer: the electrons on the outter most shell. The group # gives
the # of valence electrons.
◉ atomic size.
Answer: the size of an atom. The more electrons the bigger the size.
◉ ionization energy.
Answer: a quantity energy needed to remove one of the outer most
electrons.
◉ metallic character.
Answer: is an element that loses valence electrons
◉ To predict the charge for a representative element you-.
Answer: look at the group number its in and how many electrons it
would need to gain or lose to become stable like the noble gases.
Remember if it is gaining electrons the charge is negative because
electrons carry negative charges
