9. What are ionic radii?
Answers
Explanation:
5) Modern periodic law states that the properties of elements are in periodic functions of their atomic numbers. In the "periodic table", the atoms are arranged in the manner with respect to their atomic numbers, electronic configuration, and chemical properties. The seven rows in the "periodic table" are called periods.
6)The modern periodic table is used to organize all the known elements. Elements are arranged in the table by increasing atomic number. In the modern periodic table, each element is represented by its chemical symbol. ... Elements in the same group have similar properties.
7)Periodic Properties of the Elements
Atomic Radius.
Ionization Energy (ionization potential)
Electron Affinity.
Electronegativity.
Metallic Character.
Other Trends.
Redox Potentials. Oxidation Potential. Reduction Potential.
Uses in knowing the Periodic Properties of Elements.
8)In physics and chemistry, ionization energy or ionisation energy is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.
9)Ionic radius, rᵢₒₙ, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres .

Answer:
5. State modern periodic law
ANSWER :
Modern periodic law: The Modern periodic law states “The chemical and physical properties of elements are a periodic function of their atomic numbers”.
6. State modern periodic table
ANSWER :
Modern periodic law states that the properties of elements are in periodic functions of their atomic numbers. In the "periodic table", the atoms are arranged in the manner with respect to their atomic numbers, electronic configuration, and chemical properties. The seven rows in the "periodic table" are called periods.

8. Define ionization energy?
ANSWER:
Ionization energy is simple terms can be described as a measure of the difficulty in removing an electron from an atom or ion or the tendency of an atom or ion to surrender an electron. The loss of electron usually happens in the ground state of the chemical species.
9. What are ionic radii?
ANSWER:
Ionic radius is the distance from the nucleus of an ion up to which it has an influence on its electron cloud. Ions are formed when an atom loses or gains electrons. When an atom loses an electron it forms a cation and when it gains an electron it becomes an anion.
