EXAMS SET FULL QUESTIONS AND
COMPLETE SOLUTION
●● groups
Answer: vertical column on the periodic table
●● representative element
Answer: have group #'s 1A to 8A
●● transition elements (metals)
Answer: are the elements in between the representative elements. They
have a B next to their group numbers.
●● 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.
