Question

8. Shanice made a list about alkali metals.

Alkali Metals
Jose one electron
are found in
group one
include elements
Li, Na, and K
ions will have a
negative one
charge
Shanice made a mistake on her list. Which
best describes the mistake Shanice made?
A. Alkali metals do not lose one electron,
they gain one electron
B. Alkali metals are not found in group one;
they are found in group two.
C. Alkali metals do not include elements Li.
Na, and K, they include Al, Si, and P.
D. Alkali metal ions will not have a negative
one charge; they will have a positive one
charge

Answer 1

D. Alkali metal ions will not have a negative one charge; they will have a positive one charge

Step-by-step explanation:

Alkali metals are a found towards the left hand side of the periodic table. The comprise of Li, Na, K, Rb, Cs and Fr.

They form univalent positive ions such as Cs^+, Na^+ etc. They do not form negative ions but give out one electron to form the sort of ions stated above. Recall that metals are electropositive in nature (donate electrons).

The mistake made by Shanice is to say that group 1 elements have a negative one charge.
