Answer 1

any metal in group 1A of the periodic table

Question 2

alkaline earth metals

Answer 2

any metal in group 2A of the periodic table

Question 3

anion

Answer 3

any atom or group of atoms with a negative charge

Question 4

atomic radius

Answer 4

one half the distance between the nuclei of 2 atoms of the same element when the atoms are joined

Question 5

cation

Answer 5

any atom or group of atoms with a positive charge

Question 6

electronegativity

Answer 6

the ability of an atom to attract electrons when the atom is in a compound

Question 7

halogens

Answer 7

a nonmetal in group 7A of the periodic table

Question 8

inner transition metals

Answer 8

an element in the lanthanide or actinide series; the highest occupied s sublevel and nearby f sublevel of its atoms generally contain electrons

Question 9

ion

Answer 9

an atom or group of atoms that has a positive or negative charge

Question 10

ionization energy

Answer 10

the energy required to remove an electron from an atom in its gaseous state

Question 11

metalloids

Answer 11

an element that tend to have properties that are similar to those of metals and nonmetals

Question 12

metals

Answer 12

one of a calss of elements that are good conductors of heart and electric current; metals tend to be ductile, malleable, and shiny

Question 13

noble gases

Answer 13

an element in group 8A of the p. table; the s and p sublevels of the highest occupied energy level are filled

Question 14

nonmetals

Answer 14

an element that tends to be a poor conductor of heat and electric current; nonmetals generally have properties opposite to those of metals

Question 15

periodic law

Answer 15

when the elements are arranged in order of increasing atomic number, there is a periodic repetition of their phys and chem properties

Question 16

representative elements

Answer 16

an element in an A group in the p. table; as a group these elemetns display a wide range of phys and chem properties. In their atoms, the s and p sublevels in the highest occupied energy level are partially filled

Question 17

transition metal

Answer 17

one of the group B elements in which the highest occupied s sublevel and a nearby d sublevel generally contain electrons
