Copper was discovered in North Africa.
Answer:
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).
