Question

periodic table study guide
fill out the chart:

	na	br	kr	ca	s	ga	sb
period
group #
family name
# of valence electrons
# protons
metal, non - metal, metalloids
conducts electricity? (yes/no)
state at room temp
type of ion formed (+/- and number)

Explanation:

Step1: Use periodic table

Look up properties of each element.

Step2: Fill atomic number

Equal to number of protons.

Step3: Determine period

Row on periodic table.

Step4: Find group

Column on periodic table.

Step5: Identify family

Based on group properties.

Step6: Count valence electrons

Varies by group.

Step7: Classify element type

Metal/non - metal/metalloid.

Step8: Note conductivity

Metals usually conduct.

Step9: Note state at room temp

Solid/liquid/gas.

Step10: Determine ion type

Based on valence electrons.
