Two properties of a star is luminosity and temperature.
An ester is the reaction product between A. alcohol and organic acid.
Polarity, cohesion, adhesion, surface tension, high specific heat, and evaporating cooling
Yes thats true! You always have to think about the question or project before you start a science experiment! :)
D) energy required to remove a valence electron
Explanation:
The ionization energy is the energy required to remove a valence electron from an element.
Different kinds of atoms bind their valence electrons with different amount of energy.
- To remove the electrons, energy must be supplied to the atom.
- The amount of energy required to remove the an electron in the valence shell is the ionization energy or ionization potential.
- The first ionization energy is the energy needed to remove the most loosely bound electron in an atom in the ground state.
- The ionization energy measures the readiness of an atom to loose electrons.
