The elements from atomic numbers 1 through 118 have been discovered or synthesized, completing seven full rows of the periodic table. [1 [2 The first 98 elements all occur naturally, though some are found only in trace amounts and a few were discovered in

The modern day periodic table consists of 118 different elements, starting with hydrogen with an atomic number of one, and ending with Oganesson with an atomic number of 118. Elements are made up of three types of subatomic particles called protons, neutrons and electrons. The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 12 termed sblock elements. Groups 12 (except hydrogen) and 1318 are termed main group elements. Groups 312 are termed dblock elements. Groups 311 are termed transition elements.periodic table number 4 The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons. A stable atom would have 4 neutrons and 4

Nov 04, 2017 The elements in Group 0 of the periodic table are called the noble gases. They are unreactive because their atoms have stable arrangements of electrons. Elements in the same period have the same number of energy levels. Modern Periodic Table The elements in the periodic table are arranged in order of atomic (proton) number and so that elements periodic table number 4 Many periodic tables list numbers for element groups, which are columns of the periodic table. The elements in a group share the same number of valence electrons and thus many common chemical and physical properties. Period 5 has the same number of elements as period 4 and follows the same general structure but with one more post transition metal and one fewer nonmetal. Of the three heaviest elements with biological roles, two ( molybdenum and iodine ) are in this period; tungsten, in period 6, is heavier, along with several of the early lanthanides.
