¿Cuál(es) de las siguientes propiedades aumenta(n) a mayor Z en un grupo?

a) Primer potencial de ionización

b) Radio covalente

c) Electronegatividad

The correct answer is c) Electronegativity

Explanation:

The Z corresponds to the atomic number (defines the number of protons in the nucleus and also the electrons present in the atom). The Z increases from left to right in the same period, this is due to less shielding of the electrons in the last layer. Electronegativity (defined as the ability of the atoms to attract, in a covalent chemical bond, the electrons that it shares with other atoms), increases, the greater the Z (there is less distance).
