WebSome periodic tables have a dividing line between metals and nonmetals, and below this line, the metalloids can be found. Typically, metalloids have metallic appearances but they are usually brittle and only mediocre electricity conductors. Chemically, these elements usually behave as non-metals. Metalloids have the ability to form metallic alloys. WebHelium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. cb wavefront\u0027sWebThe alkaline earth metals are the elements that correspond to group 2 of the modern periodic table.
