Explanation:
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods
Answer:
Acceptable Lewis structure of Diatomic Nitrogen Molecule is as follow,
:N≡N:
Explanation:
The given lewis structure is acceptable because each nitrogen atom has a complete octet and and the formal charge of each nitrogen atom is zero. So those lewis structures which has zero or least formal charges are said to be more stable and acceptable. The formal charge is calculated is,
Formal Charge = # of Valence e⁻s - [# of non-bonded e⁻ + 1/2 # of bonded e⁻]
For N,
Formal Charge = 5 - [ 2 + 6/2]
Formal Charge = 5 - [ 2 + 3 ]
Formal Charge = 5 - 5
Formal Charge = 0
Same result will come for the second N atom.
During diffusion substances move from the denser medium (meaning where there is more of the substance) to less dense medium (meaning where there is less of the substance).
