Chemistry - Designing an organizational map: The periodic table
Match these items. Match the items in the left column to the items in the right column. 1. family 2. valence electrons 3. group 4. period 5. periodic table 6. octet rule
3 = a vertical column on the periodic table 4 = a horizontal row on the periodic table 5 = a table of the elements, arranged to illustrate the periodic characteristics of the elements 1 = another name for a group 6 = an atom will gain, lose, or share electrons in order to obtain eight valence electrons 2 = electrons in the outermost energy level of an atom
How many electrons will a non-metal generally have in its outer shell?
4-7
How many electrons can the 5th shell hold?
50
The element gold occurs in which period?
6th
Which element in Group IIA will have the highest melting temperature?
Be
Chlorine has 17 valence electrons.
False
Which elements are included in Group 5A?
N, P, Bi
What is a common characteristic of the transitions elements?
The next to outermost electron shell begins to fill up.
Complete the sentence. Select all that apply. The last element in any period always has:
a full valence shell the properties of a noble gas
Which of the following elements is a transition metal?
nickel
What do the elements of a period have in common? Select all that apply.
the same number of electron energy levels transition from a metal to noble gas
Which statements are correct about a group? Select all that apply.
1. Each member of the group has the identical electron configuration in the outer shell. 4. The atomic number of each element increases by 7 down through the group.
Why do the chemical properties cycle through each period?
The outermost shell of all atoms with two or more electron shells will not have more than 8 electrons.
Properties of elements can be predicted from their placement on the periodic table.
True
The Periodic Law states that the physical and chemical properties of the elements are periodic within the sequence of their atomic numbers.
True
A vertical column within the periodic table represents a family or
group
Which element is NOT in the cobalt subgroup?
iron
A horizontal row of elements in the periodic table is known as a
period
Which is the first element in the periodic table to have an electron configuration in the 4th energy level?
potassium
