Question

Which statement is not correct for the element with 1s²2s²2p⁶3s¹ electronic configuration ?

• A. This is a non-metal
• B. This is monovalent electropositive metal
• C. This element has a low electron affinity
• D. This creates basic oxide

Answer 1

Answer:

A. This is a non-metal

The correct answer is indeed This is a non-metal.

• The electronic configuration 1s²2s²2p⁶3s¹ corresponds to the element Sodium (Na), which is a metal.

Sodium has one electron in its outermost energy level (3s¹), which makes it a highly reactive metal. It readily loses this electron to form a positive ion (Na⁺), which is a characteristic of metals.

So, the statement "This is a non-metal" is not correct for the element with the electronic configuration 1s²2s²2p⁶3s¹.

Instead, the correct statements would be:

• This is a metal.

• This element is highly reactive.

• This element readily loses an electron to form a positive ion.
