WitrynaEvery atom of hydrogen has 1 proton. Until a new element is discovered, the last element on the table is element number 118. Every atom of element 118 has 118 protons. This is the biggest difference between today's periodic table and Mendeleev's periodic … WitrynaA modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column (Figure 3.2. 2 ).

WitrynaOxygen is a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
