Nonmetal oxidesreact with water to produce what are known as oxo-acids or oxyacids, i.e. acids containing NM-O-H unit, where NM = nonmetal. A non metal oxideis usually characterized by polar covalent bondsrather than the ionic bonds of a metal oxide.

Chemistry Blog: Lab Report: Metal or Nonmetal Lab
For this lab experiment, our new group, The Acids, tested sample elements A-G with the hopes in gaining enough knowledge to characterize each sample as a metal, a nonmetal, or a metalloid. To prepare for the simple, yet tedious procedure, we placed each of the seven elements on a piece of paper, and labeled them to prevent confusion.

The macrominerals sodium, magnesium, potassium, calcium, chlorine, and phosphorus are widely distributed in biological substances, although their distributions are far from uniform. Classify these elements by both their periods and their groups and then state whether each is a metal, a nonmetal, or a semimetal.
