Nonmetal - Unionpedia, the concept map

Nonmetal. Apart from hydrogen, nonmetals are loed in the p-block. Helium, as an s-block element, would normally be placed next to hydrogen and above beryllium. However, since it is a noble gas, it is instead placed above neon (in the p-block). In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes.

Silver - Wikipedia

Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table, copper and gold.Its 47 electrons are arranged in the configuration [Kr]4d 10 5s 1, similarly to copper ([Ar]3d 10 4s 1) and gold ([Xe]4f 14 5d 10 6s 1); group 11 is one of the few groups in the d-block which has a completely consistent set of electron configurations.

Quiz Question About Metals And Non-Metals - …

General physical and chemical properties of chemical elements defines elements as non-metal. Every element in the periodic table can be termed either a metal or a nonmetal.
