Answer 1

Rubidium (Rb) is the element that would most likely lose electrons to form positive ions when bonding with other elements.

Step-by-step explanation:

The element that would most likely lose electrons to form positive ions when bonding with other elements is rubidium (Rb).

Rubidium is an alkali metal found in Group 1 of the periodic table. It has only one valence electron in its outermost energy level, which makes it highly reactive. When rubidium forms ions, it loses this valence electron to achieve a stable electron configuration, resulting in the formation of a positively charged ion.

For example, rubidium can lose its valence electron to form the ion Rb+. By losing an electron, rubidium achieves the same electron configuration as the noble gas just before it in the periodic table, which is typically more stable.
