Question

the value of EI1, EI2, EI3and EI4 , of an atom are 7.5eV ,25.6eV, 48.6eV, and 170.6eV respectively . the electronic configuration of atoms will be ​

Answer 1

Explanation:

Perimeter of trapezium = 104 m

Length of Non-parallel sides = 18 m and 22 m

Altitude = 16m

Area of Trapezium = 0.5 * (sum of parallel sides)*altitude ------ (1)

Sum of parallel sides = Perimeter - (sum of non-parallel sides) = 104 m - (18+22)m = 104-40 m = 64 m

From (1), Area of Trapezium = 0.5*64*16 = 512 m^2

Ans: Area of trapezium = 512 m^2
