6) Write the atomic structure of the following elements a) Chlorine -17 b) Sodium -11 c) Carbon -6 d) Nitrogen -7 e) Helium-2
Answers
Answer:
Cl=Chlorine atom has 17 electrons.
K shell-2 electrons
L shell-8 electrons
M shell-7 electrons
Chloride ion (Cl − ) has 18 electrons. One extra electron in M-shell.
Na=Neutral sodium atom has 11 electrons whereas sodium ion (Na + ) has 10 electrons.
C=Atomic number = 6
Mass Number = 12
No. of protons = 6
No. of electrons = 6
No. of neutrons = 12 - 6 = 6
Electronic configuration - (K, L) = (2, 4)
N=Atomic Number 7
Shell structure (Electrons per energy level) [2, 5]
Electron Configuration [He] 2s2 2p3
Valence Electrons 2s2 2p3
Oxidation State -3;-2;-1 1;2;3;4;5
He=Neon and Helium are nobel gases. Neon has 10 electrons whereas helium has only 2 electrons.
