The general trend in acidity in oxides of the Period 3 elements as we go across the period from left (Group 1) to right (Group 17): basic oxides (Group 1, 2) → amphoteric oxide (Al 2 O 3) → acidic oxides (oxyacids) The same trend can be seen in each period of the Periodic table and we have: Bases react with acids such is HCl:

Synonyms (Other Words) for Nonmetal & Antonyms (Opposite Meaning) for Nonmetal.
Elements in a group have similar chemical and physical properties because they have the same number of outer electrons. Elements in a group are like members of a family--each is different, but all are related by common characteristics. Notice that each group is titled with Roman numerals and the letters A and B. Scientists in the United States and

As a result, metals are good heat and electricity conductors while non-metals are insulators. Metals are malleable and solid at room temperature whereas non-metals are brittle and can exist in the solid, liquid or gaseous state.

Group 4 is a group of elements in the periodic table. It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.

Nonmetal, or non-metal, is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties they have significantly lower melting points and boiling points than metals (with the exception of carbon). non-metals have high electronegativity.
Nonmetal definition, an element not having the character of a metal, as carbon or nitrogen. See more. These are the only stable isotopes of boron; however other isotopes have been synthesised. Boron forms covalent bonds with other nonmetals and has oxidation states of 1, 2, 3 and 4. Boron does not occur naturally as a free element, but in compounds such as borates.
