What are 5 physical properties of nickel?
The Physical Properties of Nickel are as follows:
- Color : Silvery-white metal.
- Phase : Solid.
- Conductivity: Fairly good conductor of heat and electricity.
- Ductility: It can be beaten into extremely thin sheets.
- Malleability: It’s capable of being shaped or bent.
- Luster: Exhibits a shine or glow.

What is the physical and chemical properties of nickel?
Nickel is a hard silver white metal, which forms cubic crystals. It is malleable, ductile, and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C.
What element is most similar to nickel?
The periodic table is a chart that shows how chemical elements are related to one another. Nickel is closely related to iron, cobalt, copper, and zinc. These metals are close to nickel in the periodic table.
Does magnesium have a larger atomic radius than phosphorus?
Which of the following correctly explains the atomic radius of magnesium compared to phosphorus? (a)- Magnesium has a larger atomic radius due to a smaller effective nuclear charge.
Which has the largest atomic radius sodium magnesium phosphorus or chlorine?
Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine’s valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to …
Which of the following has least radius?
Hence, Cl has the smallest radius.
Why does atomic radius decrease from top to bottom?
Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.
