In what way are elements in the same column of the periodic table the same?

• They have the same number of protons.

• They have the same number of neutrons.

• They have the same number of electrons.

• They have the same number of electrons in their valence shell.

Strontium is in Group 2 of the periodic table. Which number of electrons must be gained or lost for strontium to form a complete valence shell?

• 2 gained

• 2 lost

• 6 gained

• 6 lost

The chemical properties of an element can be best predicted by

• what state of matter it is in at room temperature

• its color and hardness

• its location on the periodic table

• its density

Which list of elements is LEAST likely to have similar chemical properties?

• Helium (He), neon (Ne), argon (Ar)

• lithium (Li), sodium (Na), potassium (K)

• fluorine (F), chlorine (Cl), iodine

• arsenic (As), selenium (Se), bromine (Br)

How are the elements arranged on the periodic table?

• alphabetical order

• increasing order of atomic number

• decreasing order of the number of valence electrons

• increasing order of the number of neutrons
