Question

1. How does the tendency of metal atoms to

lose valence electrons explain the periodic trends
of properties found in representative metal
elements

Answer 1

Step-by-step explanation:

The tendency of metals to lose electrons is a measure of their electropositivity or metallicity.

Electropositivity is a measure of the tendency of atoms of an element to lose electrons. It is closely related to ionization energy and electronegativity of an element.

• The lower the ionization energy of an element, the more electropositive or metallic an element is.
• Across a period, from left to right, electropositivity or metallicity decreases and from top to down a group, it increases.
• Metals are found on the left of the periodic table.
