Question

Give the name, give the symbol, or given the symbol, give the name for the following elements: Period 1, Period 2, Period 3, From Period 4: K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, From period 5: Ag, Sn, I, From period 6: W, Au, Pb, From period 7: U

3. Identify elements by group number and period number.

4. Identify the alkali metals, alkaline earth metals, halogens, and noble gases.

5. Identify an element as a metal, nonmetal, or metalloid.

6. Identify an element as a representative (or main group) element, transition metal, or inner transition metal.

7. Classify each element as a solid, liquid, or gas at room temperature.

8. Abbreviations, charges, and relative masses of protons, neutrons, and electrons, the nuclear model of the atom.

9. Give the number of protons, neutrons, and electrons in an atom or ion. 10. “sea of electrons” model for metals.

Answer 1

K - Potassium

Ca - Calcium

Cr - Chromium

Mn - Manganese

Fe - Iron

Co - Cobalt

Ni - Nickel

Cu - Copper

Zn - Zinc

Br - Bromine

Ag -Silver

Sn - Silver

I - Iodine

W - Tungsten

Au - Gold

Pb - Lead

U - Uranium

Elements along a vertical column in the peridic table form a group and elements along horizontal columns forms a period.

Group 1 elements are called alkali metals and group 2 elements are called alkaline earth metals.
