Answer: The ionization energies of anions of group 17 elements will be higher than for neutral atoms of the same group.
Explanation:
The ionization energy is the energy required to remove an electron from the valence shell of an isolated gaseous atom of an element.
Ionization energy depends on:
a) Electronic configuration of an element: If on losing or gaining of an electron an element attains noble gas configuration or half filled stability then it will be difficult to remove the electron from stable configuration.
b) size of an element :larger the size more lesser the effective nuclear charge on electron thus lower the ionization energy.
Group 17 elements have 7 valence electrons and thus on gaining one electron , they attain stable noble gas configuration and thus the ionization energy will become higher.
Covalent bonds are formed between nonmetals.
Explanation:
Nuclear energy is found in the nucleus of an atom holding nuclear materials in place.
When a nuclear decay or fusion occurs, the energy is released.
- Most times, the nuclear energy is transformed into heat energy.
- The heat energy is used to do other forms of work that converts energy from one form to another.
- It can be converted to mechanical energy when water is boiled and used to drive turbines.
- It can be used in heating chambers.
- this and many more can lead to energy transformation
