Periodic Trends: Metallic and Nonmetallic Character - CK-12 Foundation
WebThe reactivity of an element belonging to metals increase on moving from top to bottom in a group of the periodic table. While moving from top to bottom in a group of the periodic … WebThe most important property that differentiates non-metals from metals is their low or non-existent electrical conductivity. Electronegativities are high in non-metals. This means that non-metal atoms have a significant tendency to attract more electrons than they would otherwise have. Electronegativities in non-metals are high. cinnamon spice candle

WebMay 20, 2015 · 1 Answer. Meave60. May 20, 2015. The most reactive nonmetal is fluorine, F. The trend in reactivity in the nonmetals is the opposite of the trend in the metals. In the nonmetals, reactivity increases as you move up a group, and to the left. In the metals, reactivity increases down a group and to the right. WebIn non-metals, phosphorus, chlorine and oxygen are the most reactive. Phosphorus even catches fire if it is kept in the air. Reactivity of these non-metals can also be compared to … WebA: metals and metals, electrons freely moving B: metals and nonmetals, electrons transferred C: nonmetals and nonmetals, electrons shared D: nonmetals and metals, According to the Star Trek "Fifth Interstellar Geophysical Conference Standard" version of the periodic table, there are 140 known elements. diakoniestation leopoldshöhe-helpup
