Atomic number of Nitrogen is 7 hence Electronic configuration of Nitrogen is 1s2 2s2 2p3 Atomic number of Nitrogen is 15 hence Electronic configuration of Phosphorous is 1s2 2s2 2p6 3s2 3p3
On moving down a group in the periodic table, the number of shell increases. Because of which, valence electrons move away from the electrons and the effective nuclear charge decreases. This causes the decrease in the tendency to attract electron and hence electro negativity decreases. Because of all these reasons, Nitrogen is more electronegative than phosphorus.
Answered by Shivani Kumari | 1 year agoCompare and contrast the arrangement of elements in Mendeleev’s Periodic Table and the Modern Periodic Table.
In the Modern Periodic Table, calcium (atomic number 20) is surrounded by elements with atomic numbers 12, 19, 21 and 38. Which of these have physical and chemical properties resembling calcium?
How does the electronic configuration of an atom relate to its position in the Modern Periodic Table?
The position of three elements A, B, and C in the Periodic Table are shown below– Group 16 Group 17 - - - A - - B C
(a) State whether A is a metal or non-metal.
(b) State whether C is more reactive or less reactive than A.
(c) Will C be larger or smaller in size than B?
(d) Which type of ion, cation or anion, will be formed by element A?
An atom has electronic configurations 2, 8, 7.
(a) What is the atomic number of this element?
(b) To which of the following elements would it be chemically similar? (Atomic numbers are given in parentheses.) N(7), F(9), P(15), Ar(18)
