Let's solve the problem step by step.
We are asked to classify each element as:
-
M – Metal
-
NM – Non-metal
-
ML – Metalloid
Here’s the classification for each element:
---
1.
Gold
- Gold (Au) is a shiny, conductive, malleable element found on the left side of the periodic table.
- It is a
metal.
✔ Answer: M
2.
Silicon
- Silicon (Si) is located on the border between metals and non-metals in the periodic table.
- It has properties of both metals and non-metals (e.g., semiconductor behavior).
- It is a
metalloid.
✔ Answer: ML
3.
Nitrogen
- Nitrogen (N) is a gas at room temperature, does not conduct electricity, and is located on the right side of the periodic table.
- It is a
non-metal.
✔ Answer: NM
4.
Neon
- Neon (Ne) is a noble gas, colorless, odorless, and inert.
- It is a
non-metal.
✔ Answer: NM
5.
Boron
- Boron (B) is located on the border between metals and non-metals.
- It has characteristics of both, such as being a poor conductor but forming covalent compounds.
- It is a
metalloid.
✔ Answer: ML
6.
Copper
- Copper (Cu) is a shiny, ductile, and highly conductive metal.
- It is a
metal.
✔ Answer: M

Final Answers:
1. Gold :
M
2. Silicon :
ML
3. Nitrogen :
NM
4. Neon :
NM
5. Boron :
ML
6. Copper :
M
✔ These classifications are based on their positions in the periodic table and physical/chemical properties.
