Which of these is correct?
As you move down a group, the atomic radius increases because -
you add more and more neutrons
you add more and more protons
you add more and more shells (energy levels)
you add more atomic mass
As you move across the periodic table from left to right, the atomic radius decreases. This is because -
the number of protons increases, so attraction to electrons increases
the number of energy levels increases
the number of electrons increases
the atomic mass increases
Which atom has the largest atomic radius in Period 4 (row 4)?
K
Kr
Fe
Fe
Francium (Fr) has the lowest ionization energy in Group 1 because -
It has the smallest number of valence electrons
It has the greatest atomic mass
It has the greatest number of protons, so it attracts its electrons the strongest
Its one valence electron is very far from the nucleus, so little energy is needed to remove it
All groups/families have similar
Names
Atomic numbers
Atomic masses
Properties
The atom with the largest atomic radius in Period 4 (row 4) is -
K
Kr
Fe
Arrange the following in order of increasing ionization energy: Strontium, Aluminum, Indium.
Strontium, Indium, Aluminum
Strontium, Aluminum, Indium
Indium, Aluminum, Strontium
Aluminum, Indium, Strontium
The trend seen in the periodic table for valence electron number is:
they increase across a period and match the group number.
they decrease across a period and match the group number.
they increase across a period and match the period number.
they decrease across a period and match the period number.
The trend seen in the periodic table for energy level number is:
they increase down a group.
they decrease down a group.
How did Chemists begin the process of organizing elements?
They assigned them in order as they were discovered.
They looked at the subatomic particles of the elements found and organized them in increasing order.
They used properties of the elements to sort them into groups.
There was not an order until after the year 1700 since they could not yet identify all of the elements.
The trend seen in the periodic table for proton number is:
they increase across a period.
they decrease across a period.
The trend seen in the periodic table for electron number (in neutral atoms) is:
they increase across a period.
they decrease across a period.
The trend seen in the periodic table for energy level number is:
they increase down a group.
they decrease down a group.
The trend seen in the periodic table for valence electron number is:
