Periodic table

On the periodic table, a period is a

• Column

• Dot

• Row

• Group

On the periodic table, a group is a

• Row

• Column

• Block

• Bunch of elements that have the same atomic number

To find atomic mass, add

• Protons and electrons

• Electrons and neutrons

• Protons, electrons, and neutrons

• Protons and neutrons

Atomic number is the number of

• Protons

• Neutrons

• Protons plus neutrons

• Electrons, protons, and neutrons added together

The number of these in a particular atom is generally the same.

• Protons and electrons

• Protons and neutrons

• Neutrons and electrons

• Protons, neutrons, and electrons

The electrons on the outer shell are called

• Border electrons

• Outside electrons

• Valence electrons

• Bond electrons

If the outer shell is at capacity with electrons

• The atom cannot bond with another atom

• The atom can bond only with atoms of the same element

• The atom can bond with all other atoms

• One electron will jump to another shell

The elements in each group have

• The same number of shells

• The same number of valence electrons

• The same number of electrons

• The same number of protons

The elements in each period have

• The same number of shells

• The same number of valence electrons

• The same number of electrons

• The same number of protons

If two atoms have the same number of protons,

• They are the same element

• They can always bond with each other

• They may have a different number of electrons

• They may be different elements
