Interpretation: The total number of electrons in the given ionsneeds to be determined.
Concept introduction:Charge tells the number of electrons more or less than number of electrons present in the neutral state. For a neutral atom, charge is zero but if an electron is removed, atom becomes positive charge and if an electron is added, atom becomes negative charge.
Answer to Problem 38A
Explanation of Solution
To find the total number of electrons present in the negative ions given, first note the
Then, note the charge given and add them to the atomic number.
Therefore,
Negative ions | Atomic number | Total number of electrons |
34 | 36 | |
16 | 18 | |
15 | 18 | |
8 | 10 | |
7 | 10 | |
53 | 54 | |
9 | 10 | |
17 | 18 | |
35 | 36 | |
85 | 86 |
Positive ions means it will loss electrons and negative ions means it will gain electrons to reach the noble gas configuration.
