can you name some reactive nonmetals mentioned in the table?
Selenium, iodine, fluorine
Nonmetal
Of the solids, graphite carbon, selenium, and iodine are metallic-looking, whereas S sulfur has a pale-yellow appearance. Ordinary white phosphorus has a yellowish-white appearance but the black allotrope, which is the most stable form of phosphorus, has a metallic-looking appearance.
name of a row in the periodic table The seven rows of the table, called periods what is this table about? It is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties can you name some chemical elements? Hydrogen, oganesson, plutonium what is the atomic number of the first element? Atomic numbers 1 can you name some things that react with this element? Chlorine and fluorine what are some of its isotopes? Deuterium, tritium, protium who was the first to discover it? Henry Cavendish was the first to recognize hydrogen gas, and Antoine Lavoisier gave the element the name hydrogen what precautions does one have to take while dealing with this element? UNANSWERABLE does the table also contain information about metals? Yes where are the metals and nonmetals placed on the table? The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. when was the first table published? 1869 and by whom? Russian chemist Dmitri Mendeleev where is he from? Russia can you tell me some achievements that he has made? He investigated the expansion of liquids with heat, and devised a formula similar to Gay-Lussac's law of the uniformity of the expansion of gases, while in 1861 he anticipated Thomas Andrews' conception of the critical temperature of gases by defining the absolute boiling-point of a substance what else interested him apart from chemistry? Russian industry, technical issues in agricultural productivity, demographic issues, measuring the efficacy of chemical fertilizers, and promoted the merchant navy.

Nonmetal [SEP] Reactive nonmetal
The reactive nonmetals have a diverse range of individual physical and chemical properties. In periodic table terms they largely occupy a position between the weakly nonmetallic metalloids to the left and the noble gases to the right. Physically, five are solids, one is a liquid (bromine), and five are gases. Of the solids, graphite carbon, selenium, and iodine are metallic-looking, whereas S sulfur has a pale-yellow appearance. Ordinary white phosphorus has a yellowish-white appearance but the black allotrope, which is the most stable form of phosphorus, has a metallic-looking appearance. Bromine is a reddish-brown liquid. Of the gases, fluorine and chlorine are coloured pale yellow, and yellowish green.
