Concept explainers
Fill in the blanks in each line in the following table. The first line is already completed as an example.
(a)
Interpretation:
Filling of each blank in the following table has to be done:
Concept Introduction:
Atoms are composed of three types of particles called subatomic particles. They are as follows:
- Protons: Positively charged particles in an atom.
- Neutrons: Neutral charged particles in an atom.
- Electrons: Negatively charged particles in an atom.
The neutral atom has equal number of protons and electrons. Gaining or loosing of electrons of an atom forms ion.
Negative charged ions are formed by gaining one or more electrons and it has more electrons than protons.
Positive charged ions are formed by losing one or more electrons and it has more protons than electrons.
Answer to Problem 4.28EP
Complete table is shown below:
Explanation of Solution
The charge on an ion and its magnitude is equal to the number of protons minus the number of electrons.
The given ion has
Hence, the symbol of ion is
