Write Metals: , Non-Metals: & Metalloids: in Answer part.

Question

Classify the following as Metals, Non-Metals & Metalloids: CI, K, Ca, Sn, B, Br, Na, Al, Ba, Ne, O, N, H, Fe, Ag, Au, Co, Cr, U, Zn, Cu, Pb, F, Si, Ge, C.

Answer 1

Metals:

- K (Potassium)
- Ca (Calcium)
- Sn (Tin)
- Na (Sodium)
- Al (Aluminum)
- Ba (Barium)
- Fe (Iron)
- Ag (Silver)
- Au (Gold)
- Co (Cobalt)
- Cr (Chromium)
- U (Uranium)
- Zn (Zinc)
- Cu (Copper)
- Pb (Lead)

Non-Metals:
- CI (Chlorine)
- B (Boron)
- Br (Bromine)
- Ne (Neon)
- O (Oxygen)
- N (Nitrogen)
- H (Hydrogen)
- F (Fluorine)
- C (Carbon)

Metalloids:
- Si (Silicon)
- Ge (Germanium)

The classification is based on the properties of these elements. Metals are typically good conductors of electricity, have a shiny appearance, and are malleable and ductile. Non-metals are usually poor conductors of electricity, and their physical properties can vary widely. Metalloids have properties that are intermediate between metals and non-metals, and they often exhibit characteristics of both categories.
