Which of the following groups of elements all have 5 valence electrons? Select one: 0 N/P / As / Sb 0 0/S / Se / Te 0 Li / Na / K / Rb 0 F/CI / Br / | C / Si / Ge / Sn B / Al / Ga / In Check
The Correct Answer and Explanation is:
Correct Answer:
N / P / As / Sb
Explanation:
The correct answer is the group containing Nitrogen (N), Phosphorus (P), Arsenic (As), and Antimony (Sb). The number of valence electrons an element possesses is determined by its position in the periodic table, specifically its group number. Valence electrons are the electrons located in the outermost shell of an atom, and they are the primary electrons involved in chemical bonding.
Elements within the same vertical column, or group, of the periodic table share similar chemical properties because they have the same number of valence electrons. To find the group of elements with 5 valence electrons, we must examine the group placement for each option.
- N / P / As / Sb: These elements are all located in Group 15 of the periodic table, also known as the pnictogens. For main-group elements in Groups 13-18, the number of valence electrons can be found by subtracting
