Explanation:
From the question given, all element belong to the same group in the periodic table and there names are Nitrogen, Phosphorous, Arsenic and Antimony respectively.
Using the periodic table,
Element N
From the periodic table, the element N is called Nitrogen and it's atomic number is 7 atomic mass is 14, the number of outermost electron in N is 5.
For N
- Name = Nitrogen
- atomic number = 7
- atomic mass = 14amu
- outermost electron = 5
Element P
From the periodic table, the element P is called phosphorous and it's atomic number is 15, atomic mass is 30.97amu and it has 5 electrons on it's outer shell.
For P
- Name = Phosphorous
- atomic number = 15
- atomic mass = 30.97 amu
- outermost electron = 5
Element As
From the periodic table, the element As is called Arsenic and it's atomic number is 33 and atomic mass is 74.92 amu and it has 5 outermost or valence electrons.
For As
- Name = Arsenic
- Atomic number = 33
- Atomic mass = 74.92 amu
- Valance electrons = 5
Element Sb
From the periodic table, the element Sb is called Antimony and it's atomic number is 51 atomic mass is 121.76 amu and it has 5 valence electrons.
For Sb
- Name = Antimony
- Atomic Number = 51
- Atomic mass = 121.76 amu
- Valence electrons = 5
