For example, elements in the metals class can conduct electricity, whereas elements in the nonmetals class generally cannot. Elements in the metalloids class fall in between the metals and nonmetals in their properties. An example of a metalloid is arsenic
What type of ions do nonmetals naturally form? 1: …
Answer: 1: Negative ions, by gaining electrons to fill the valence shell Explanation: Nonmetals gain the electron to complete the octet and form anion. Consider the example of halogen. When it coine with metals it gain the electron from the metal and form anion.
