Which elements have the most similar chemical properties?
Mumz [18]

Answer: K and Na

Explanation:

Potassium and Sodium have a chemical symbol of K and Na respectively.

They have similar chemical properties because both

- have only one valence electron,

- form univalent positive ion when they donate their lone outermost electron as shown below

Na --> Na+ + e-

K --> K+ + e-

- are good reducing agents

- react with cold water vigorously to liberate hydrogen gas and form alkalis, so they are known as alkali metals.

- K and Na are placed in Group 1 of the periodic table.

Thus, unlike the other pairs given, K and Na, have the most similar chemical properties

REY [17]

Answer:

pH = 4.34

Explanation:

pH= -1/2(logKa) -1/2(log C)

= -1/2( log 5.98*10^-8) -1/2(log 0.0353)

=-1/2(-7.22)-1/2(-1.45)

=3.61+0.725= 4.34
