What are the vertical columns called groups. Atoms of each element within a group have the same number of electrons in their outermost electron shell. Elements belonging to one of the 18 groups will share similar properties. Examples of groups of elements that are nonmetals are the nonmetals (of course), the halogens, and the noble gases. What are the columns on the periodic table organized by Each vertical column on the periodic table is called a group. Examples of groups of elements that are metals include alkali metals, alkaline earths, basic metals, and transition metals. These elements are called metalloids or semimetals. There are also elements with properties intermediate between metals and nonmetals. The two main types of elements are metals and nonmetals.The exception is the elements at the very end of the periodic table, which have placeholder names (until they are officially discovered and named) and three-letter symbols. The element symbol is a shorthand notation that is either one capital letter or a capital letter and a lowercase letter. The exact information given for the element varies, but there is always the atomic number, the symbol for the element, and the atomic weight. Each element has its tile or cell in the periodic table.The top row goes with period 6, while the bottom row goes with period 7. These rows of elements, the lanthanides and actinides, are special transition metals. They are placed there because there wasn't room to put them where they should go. There are two rows of elements found below the main body of the periodic table.For example, elements of the halogen group all have a valence of -1 and are highly reactive. Atoms of each element within a group have the same number of electrons in their outermost electron shell. 7 What are the vertical columns in the Periodic Table called 8 How many electrons are there Make sure you understand these KEY TERMS terms before moving. Each vertical column on the periodic table is called a group.As you move from left to right across a period, elements transition from displaying metal characteristics toward nonmetallic properties. Elements in the same period all have the same electron ground state energy level. There are seven periods on the periodic table. Each horizontal row on the periodic table is called a period.The original table organized the elements by increasing atomic weight. This is the biggest difference between today's periodic table and Mendeleev's periodic table. Every atom of element 118 has 118 protons. Until a new element is discovered, the last element on the table is element number 118. So element number 1 (hydrogen) is the first element. The atomic number is the number of protons in an atom of that element. Elements are listed in numerical order by atomic number.
