QuestionWhich element is chemically similar to calcium (Ca)? A) K B) Sr C) Sc D) S E) Ga
Studdy Solution
STEP 1
Assumptions1. The chemical similarity of elements is determined by the number of valence electrons they have.
. Elements in the same group (column) of the periodic table have the same number of valence electrons.
3. Calcium (Ca) is in Group of the periodic table.
STEP 2
We need to identify which of the given elements is also in Group2 of the periodic table.
STEP 3
Potassium (K) is in Group1 of the periodic table.
STEP 4
Strontium (Sr) is in Group2 of the periodic table.
STEP 5
Scandium (Sc) is in Group3 of the periodic table.
STEP 6
ulfur () is in Group16 of the periodic table.
STEP 7
Gallium (Ga) is in Group13 of the periodic table.
STEP 8
From the above steps, we can see that Strontium (Sr) is the only element in the same group as Calcium (Ca), which is Group2. Therefore, Strontium (Sr) is chemically similar to Calcium (Ca).
The answer is B) .
