Question

1. metals tends to __i electrons to become ii__ ions

the statement above is best completed by the answers in row:

row	i	ii
	lose	negative
	gain	positive
	lose	positive

Explanation:

To solve this, we recall the behavior of metals in chemical reactions. Metals have low electronegativity and tend to lose electrons. When an atom loses electrons, it has more protons than electrons, so it becomes a positive ion (cation). Let's analyze each row:

• First row: Metals don't gain electrons to be negative (non - metals gain electrons to be negative), so incorrect.
• Second row: Losing electrons gives a positive, not negative ion, so incorrect.
• Third row: Metals lose, not gain electrons to be positive, so incorrect.
• Fourth row: Metals lose electrons and become positive ions (cations), which is correct.

Answer:

The row with "lose" in column i and "positive" in column ii (the last row in the table).
