In the modern form of Periodic Table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
In the periodic table a column is the elements that go down the way.for exampleLiNaKRbCsFrThis is a column and called the Alkali metals. Group 1.A period is when it goes across.

Because the Periodic table of the Elements read from left to right goes in order of the amount of protons in each element.
A star is made up of Hydrogen and Helium, (the Helium coming from the fusion of Hydrogen atoms). When a star goes super nova, it is so hot that it fuses together gases so rapidly that it creates all of the elements on the periodic table.
No, the periodicity of the Periodic Table of Elements refers to the fact that the chemical properties of elements vary in a periodic way, from metals on the left hand side of the table to non-metals and then to noble gases in the far right hand column. Each row goes through the same variations. There is nothing periodic about the increase in mass; that would be described as a linear progression rather than a periodic phenomenon.
In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.
In the periodic table a column is the elements that go down the way.for exampleLiNaKRbCsFrThis is a column and called the Alkali metals. Group 1.A period is when it goes across.
mendaleev went by atomic #, where as the modern table goes bt atomic mass. answer it?

There are 91 natural elements. These can be found naturally everywhere in the world. However, new elements have been artificially made in a laboratorium. So far, 27 elements have been made by humans, leaving a total of 118 elements on the periodic table. However, these synthetic elements can't be considered real elements, since they disappear almost as fast as they were made. For instance, ununoctium's (element number 118) most stable isotope has a half-life of 0.00089 seconds. But in the Extended version of the periodic table it goes all the way up to element 173 but no research has been found yet.....EXTENDED PERIODIC TABLE:11H2He23Li4Be5B6C7N8O9F10Ne311Na12Mg13Al14Si15P16S17Cl18Ar419K20Ca21Sc22Ti23V24Cr25Mn26Fe27Co28Ni29Cu30Zn31Ga32Ge33As34Se35Br36Kr537Rb38Sr39Y40Zr41Nb42Mo43Tc44Ru45Rh46Pd47Ag48Cd49In50Sn51Sb52Te53I54Xe655Cs56Ba57La58Ce59Pr60Nd61Pm62Sm63Eu64Gd65Tb66Dy67Ho68Er69Tm70Yb71Lu72Hf73Ta74W75Re76Os77Ir78Pt79Au80Hg81Tl82Pb83Bi84Po85At86Rn787Fr88Ra89Ac90Th91Pa92U93Np94Pu95Am96Cm97Bk98Cf99Es100Fm101Md102No103Lr104Rf105Db106Sg107Bh108Hs109Mt110Ds111Rg112Cn113Uut114Uuq115Uup116Uuh117Uus118Uuo8119Uue120Ubn121Ubu122Ubb123Ubt124Ubq125Ubp126Ubh127Ubs128Ubo129Ube130Utn131Utu132Utb133Utt134Utq135Utp136Uth137Uts138Uto139Ute140Uqn141Uqu142Uqb143Uqt144Uqq145Uqp146Uqh147Uqs148Uqo149Uqe150Upn151Upu152Upb153Upt154Upq155Upp156Uph157Ups158Upo159Upe160Uhn161Uhu162Uhb163Uht164Uhq165Uhp166Uhh167Uhs168Uho9169Uhe170Usn171Usu172Usb173Ust170Usn171Usu172Usb173UstActually, there are 117 elements on the periodic table. But, they couldn't make element number 117 so it's 1-116 and then 118.There are 118 elements in the periodic table (March 2013).
Because the Periodic table of the Elements read from left to right goes in order of the amount of protons in each element.
one goes sideways and one goes up and down. its just a way to locate the elements easier
Yes they do. The group goes Be, Mg, Ca, Sr, Ba, Ra
A star is made up of Hydrogen and Helium, (the Helium coming from the fusion of Hydrogen atoms). When a star goes super nova, it is so hot that it fuses together gases so rapidly that it creates all of the elements on the periodic table.

The Periodic Table of elements has gone through several arrangments, but the current (and correct) arrangement goes from lowest to highest atomic number (number of protons). i.e. Hydrogen has 1 proton, Helium has 2 protons, etc.
it goes up and down
