10.
What is the Periodic Table?
a)
A table that labels the different geologic time periods.
b)
Another term for a school schedule
c)
a table of the chemical elements arranged in order of atomic mass, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
d)
a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
11.
What is a period? (As it relates to science you dirty minded people.)
( ͡° ͜ʖ ͡°)
( ͡° ͜ʖ ͡°)
a)
relating to the periodic table of the elements or the pattern of chemical properties that underlies it.
b)
( ͡° ͜ʖ ͡°)
c)
appearing or occurring at intervals.
12.
Define Group/Family (SCIENCE)
a)
*starts singing*
I love you, you love me, we're a happy group/family
I love you, you love me, we're a happy group/family
b)
A family refers to a group of elements with similar chemical properties. Chemical families tend to be associated with the vertical columns on the periodic table. Also Known As: Groups. Examples: Group 18 on the periodic table is also known as the noble gas family.
c)
Definition: In Chemistry, family refers to a group of elements with similar chemical properties. Chemical families tend to be associated with the vertical columns on the periodic table. Also Known As: Groups. Examples: Group 5 on the periodic table is also known as the noble gas family.
d)
Hint: the answer isn't g5.
13.
What's a metal
a)
They give them out at the olympics. duh
b)
Elements that form cations when compounds of it are in solution and oxides of the elements form hydroxides rather than acids in water. Most metals are conductors of electricity, have crystalline solids with a metallic luster and have a high chemical reactivity.
c)
.______. plastic?
d)
Elements that form cations when compounds of it are in solution and oxides of the elements form hydroxides rather than acids in water. Most metals aren't conductors of electricity, have crystalline solids with a metallic luster and have a high chemical reactivity.
