question 10. complete the table below by classifying each element as a metal, metalloid, or nonmetal. then, identify the group name to which each element belongs.\nelement metal, metalloid, or nonmetal group name\nmagnesium (mg)\nchlorine (cl)\nzirconium (zr)\npotassium (k)\nradon (rn)\nastatine (at)\nhelium (he)\nbromine (br)\nrubidium (rb)\nstrontium (sr)
Answer
Explanation:
Step1: Recall element properties
Magnesium is a metal in Group 2 (alkaline - earth metals).
Step2: Identify chlorine
Chlorine is a non - metal in Group 17 (halogens).
Step3: Determine zirconium
Zirconium is a metal in Group 4 (transition metals).
Step4: Classify potassium
Potassium is a metal in Group 1 (alkali metals).
Step5: Identify radon
Radon is a non - metal in Group 18 (noble gases).
Step6: Determine astatine
Astatine is a metalloid in Group 17 (halogens).
Step7: Classify helium
Helium is a non - metal in Group 18 (noble gases).
Step8: Identify bromine
Bromine is a non - metal in Group 17 (halogens).
Step9: Determine rubidium
Rubidium is a metal in Group 1 (alkali metals).
Step10: Classify strontium
Strontium is a metal in Group 2 (alkaline - earth metals).
