Question

four properties are listed below. match each property with the correct definition. place the correct property in blanks 17 - 20.
a. atomic radius b. electronegativity
c. ionic radius d. ionization energy
______17. a measure of the force of attraction between an atom and a shared pair of electro - covalent bond.
______18. the distance from the nucleus to the valence shell of an atom.
______19. the distance from the nucleus of a charged atom to the outer shell of electrons.
______20. the energy required to remove the outermost electron from a neutral atom.
multiple choice:

Explanation:

• 17: Electronegativity is defined as a measure of the force of attraction between an atom and a shared pair of electrons in a covalent bond.
• 18: Atomic radius is the distance from the nucleus to the valence shell of an atom.
• 19: Ionic radius is the distance from the nucleus of a charged atom to the outer shell of electrons.
• 20: Ionization energy is the energy required to remove the outermost electron from a neutral atom.

Answer:

1. B. Electronegativity
2. A. Atomic Radius
3. C. Ionic Radius
4. D. Ionization Energy
