The presence of hydrogen and hydroxyl ions determines the acidic and basic nature of a solution.
<h3>What determine acidic and basic nature of a solution?</h3>
The use of the pH scale is one way of determining the acidic and basic nature of solution. If the pH of a solution is less than 7, it is considered as acidic and if the pH is 7, the solution is neutral.
While if the pH is greater than 7,the solution is basic so we can conclude that the presence of hydrogen and hydroxyl ions determines the acidic and basic nature of a solution.

Answer:
d) Metallic character decreases as you go to the right across a row in the periodic table and increases as you go down a column.
Explanation:
- <em><u>Metallic character decreases as you move across a period in the periodic table from left to right.</u></em> This is because the attraction between valence electron and the nucleus increases, making it difficult for loss of electrons. It occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell.
- On the other hand, <em><u>Metallic character increases as you move down an element group in the periodic table.</u></em> This is due to the increase in atomic radius as the number of energy levels increases.
