Question
The total number of semi-metals among the following is:
- Si
- Sb
- Ge
- Ga
- As
- Sn
- Se
- 52
- 43
- 34
- 2
Solution
To determine the total number of semi-metals among the given elements (Si, Sb, Ge, Ga, As, Sn, Se), we need to identify which elements are classified as semi-metals.
- Si (Silicon): Silicon is a semi-metal.
- Sb (Antimony): Antimony is a semi-metal.
- Ge (Germanium): Germanium is a semi-metal.
- Ga (Gallium): Gallium is not a semi-metal.
- As (Arsenic): Arsenic is a semi-metal.
- Sn (Tin): Tin is not a semi-metal.
- Se (Selenium): Selenium is not a semi-metal.
Based on this analysis, we can conclude that there are a total of 3 semi-metals among the given elements.
