8) how many valence electrons do the alkaline earth metals have?\n2\n4\n6\n7\n9) which of the following elements has the same electron dot structure as nitrogen?\nsilicon\ncarbon\narsenic\nhelium

8) how many valence electrons do the alkaline earth metals have?\n2\n4\n6\n7\n9) which of the following elements has the same electron dot structure as nitrogen?\nsilicon\ncarbon\narsenic\nhelium

Answer

Brief Explanations:

Alkaline Earth Metals are in Group 2 of the periodic table and have 2 valence electrons. Elements in the same group have the same number of valence electrons and thus the same electron - dot structure. Nitrogen is in Group 15, and arsenic is also in Group 15.

Answer:

  1. 2
  2. arsenic
