Answers
1
How is the periodic table organized?
All of the above
By the number of electron energy levels that there are
By their atomic number
By the number of electrons in the outer shell
2
Transitional metals are
poor conductors of heat and electricity
All silvery metals
None of the above
they have a low D and MP
3
Group 17 is the
Metals
halogens
nonmetals
metalloids
4
Metals are found to the right of the zigzag line and have lots of electrons in their outer shell.
True
False
5
Metalloids are the zig zag line.
False
True
6
Group 1 and 2 are the most reactive metals because they
Have just 1 or 2 e’ in their outer shell
They want to have a complete outer shell of e’
only found combine w/ other elements in nature because of high reactivity
These elements readily form compounds
7
Rows or Periods go left to right and follow a repeating or periodic pattern that
Connects them with similar chemical and physical properties
conductivity (of electricity)
increase the number of e’ in the outer shell
Increase in the # of P
8
Groups have similar:
None of the above
All of the above
chemical properties
There are no groups on the periodic table
physical properties
are often referred to as families
9
Most elements are metals
True
False
10
Most metals are good conductors of electricity, malleable, ductile, and shiny
False
True
11
All metals are solid at room temperature.
True
False
12
Metalloids
are solid at room temperature
Have properties of both metals and nonmetals
Are reactive, but it varies
all of the above
13
Noble gasses are nonmetals
True
False
14
What is a nonmetal?
they are found to the right of the zigzag line
all of the above
more than half are gasses at room temperature
they have almost complete outer electron layers
15
Group numbers are columns- up and down while periods go left to right.
True
False
16
Lanthanides follow the element Lanthanum or La, are all
Radioactive
shiny, reactive metals
nonradioactive
all of the above
17
Which of the following are less dense than water
Potassium K
Sodium Na
Lithium Li
metals can not be less dense than water
18
Metalloids are also considered to be semiconductors.
False
True
19
Noble gasses
All of these are correct!!!
Found on the far left of the table, radioactive, usually inert gasses
Contain nonmetals, Unreactive, colorless/odorless gasses
discovered by royalty, highly volatile, used in chemical warfare
20
The group number or family, tells us
same # of e’ in the outer shell
number of energy levels, like on a Bohr model
They will have similar properties (but not always)
none of these
21
Metalloids have their outer electron levels about ½ full
True
False
22
Actinides follow the element Actinium, or Ac are all
all of the above
shiny, reactive metals
nonradioactive
Radioactive
23
Group 13-16 are
metalloids
Metals
non metals
noble gasses
24
What is the periodic table?
D) The table I eat from time to time
list of the 98 naturally occurring elements on Earth (1-92 except 46 & 61)
a list of all the known elements in the universe.
lists all the 118 elements we know of including nearly 30 created by people
25
Some properties of nonmetals include
poor conductors of electricity and thermal energy
not shiny
are brittle -break or shatter with a hammer
not malleable or ductile
26
Group 2, the Alkaline-earth metals are less reactive than group 1, the Alkali metals because
They are less dense than alkali metals
All of the above
They are often found in compounds
It’s harder to give away 2 e’ than one
27
Metalloids only share properties of nonmetals.
False
True
28
Halogens
have 8 e’ in the outer shell, are non reactive, good conductors
Have 7 e’ in the outer shell, are very reactive, poor conductors electrity
I thought halogens were lights?
nonmetals, radioactive, and can be deadly
29
3. What are the 3 main categories of elements in the periodic table?
Metals, nonmetals, radioactive elements
Metals, Nonmetals, metalloids
Radioactive, Non-reactive, stable elements
Country, Rock, Jazz
