Question

The atomic numbers of elements X , Y and Z are 17 , 19 , 20 respectively . The number of electrons present in the M shell of these elements follow the order
Z > X > Y
X > Y > Z
X < Y = Z

Answer 1

Answer:

the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

"courses in algebra, geometry, and Newtonian physics"

Answer 2

Explanation:

The atomic numbers of elements x/y and z are 19 21 and 25 respectively the number of electrons present in the M shells of these elements follow the order

The atomic numbers of elements x/y and z are 19 21 and 25 respectively the number of electrons present in the M shells of these elements follow the orderTherefore, the electron distribution of X, Y, Z with atomic number 19,21 and 25 respectively. From this electronic distribution the number of electrons of X, Y, Z elements in the M shell are 9, 11, 15 respectively. The order of electrons in M shell isz>y>x.
