Answer 1

Here are the classifications for each element based on the periodic table:

• Radium (Ra - Atomic number 88) Metal

• Germanium (Ge - Atomic number 32) Metalloid

• Selenium (Se - Atomic number 34) Nonmetal

• Cobalt (Co - Atomic number 27) Metal

• Xenon (Xe - Atomic number 54) Nonmetal

• Silicon (Si - Atomic number 14) Metalloid

So the answers are as follows:

• Radium (Ra): Metal
• Germanium (Ge): Metalloid
• Selenium (Se): Nonmetal
• Cobalt (Co): Metal
• Xenon (Xe): Nonmetal
• Silicon (Si): Metalloid
