Which element has the same number of valence electrons as As (arsenic)?A.Sb (antimony)B.Ge (germanium)C.Al (aluminum)D.Se (selenium)SUBMITarrow_backPREVIOUS
Solution
The element that has the same number of valence electrons as As (arsenic) is Sb (antimony).
Here's the step-by-step explanation:
-
First, we need to know the number of valence electrons in As (arsenic). Arsenic is in Group 15 of the periodic table, so it has 5 valence electrons.
-
Then, we look at the options given. We need to find an element that also has 5 valence electrons.
-
Sb (antimony) is also in Group 15 of the periodic table, so it also has 5 valence electrons.
-
Therefore, Sb (antimony) has the same number of valence electrons as As (arsenic).
So, the answer is A. Sb (antimony).
