b) Magnesium
: 3, 0, 0, -1/2
c) Iodine: 5, 1, 0, -1/2
d) Cadmium: 4, 2, 2, -1/2
Explanation:
To understand Chemistry in its true sense, it is necessary to know the way the electrons are arranged within the atom and also understand the how and why of the bond and reactivity. To do this, you must first know the how and why of the electronic structure. , this can be done with quantum numbers.
The quantum numbers are four and they help us to describe the place of the electrons in the vicinity of the nucleus.
For the number less than 0.1 such as 0.006, the zeroes to the right of the decimal point but before the first non zero digit show the decimal place of the first significant digit.
- The number that is given as digits is established using significant figures.
- Any two non-zero digits that are separated by a zero are significant figure.
- Every zero that is both to the right and left of a non-zero digit and the decimal point is not significant figure.
- The quantity of significant figures frequently reveals the degree of measurement accuracy. From the first non-zero digits in the figure, we may determine the number of significant figures.
There is only one significant figure in the provided number 0.06. The decimal place of the first digit is indicated by the zeros that appear to the right of the decimal point but before the first non-zero digit.
