• Periods . Answer: horizontal rows on the periodic table
• 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.
• 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
• To predict the charge for a transition metal . Answer: look at the roman
numerals in the name and that would be the charge for the element
