What is pH value in simple words?

The pH value is a measure of how acidic/basic a substance is.

The range goes from 0 to 14, with 7 being neutral.

pH values that are less than 7 indicate acid (acidity), whereas a pH value greater than 7 indicates a base (basic).

pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the substance.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
