In chemical reactions, they tend to form positive ions (cations) as they lose negative electrons. Physically, metals tend to be shiny and malleable, and they are good conductors of heat and electricity. This large category of elements includes some of the most famous elements of all time. ...
Elements in the same group often have similar chemical properties ___ they have the same number of valence electrons. A. because B. so C. but D. or 相关知识点: 试题来源: 解析 A。因为同一组的元素具有相似的化学性质是因为它们有相同数量的价电子,所以用 because。
Titanium's chemical properties resemble those of zirconium and silica, which are also in Group 4 (IVB) of the periodic table. Elements in this group share similar chemical characteristics and exhibit properties that place them between metals and nonmetals. Like magnesium and aluminum, titanium and...
