Question

Which is the symbol for the element that contains 28 electrons in each of its neutral atoms?

• A. $V$
• B. $Ni$
• C. $N$
• D. $S$
• E. $Si$

Answer 1

Answer: (B)

$Ni$

Nickel is a chemical element with symbol $Ni$ and atomic number $28$. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation).
