Nonmetals (nonmetals, halogens, and noble gases):

Under certain circumstances, several metalloids can conduct electricity.Have physical properties more like nonmetals.Metals (alkali metals, alkali earth metals, lanthanides, actinides, transition metals, and post-transition metals):.These three big groups are metals, metalloids, and nonmetals.Įach of these three big groups has different traits generally. We can group these ten again into three big groups if we want. Noble gases (He, Ne, Ar, Kr, Xe, Rn, Og): colorless, odorless, and nonreactive.Halogens (F, Cl, Br, I, At, Ts): quite reactive chemically.Nonmetals (C, N, O, P, S, Se): are a poor conductor.Metalloids (B, Si, Ge, As, Sb, Te, Po): have conductor/semiconductor properties.Post-transition metals (Al, Ga, In, Sn, Tl, Pb, Bi, Nh, Fl, Mc, Lv): have characteristics similar to transition metals but softer and are a worse conductor.Actinides (Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr): radioactive.Lanthanides (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu): have a silver color and tarnish when contacting air.Transition metals (Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Cn): malleable, shiny, and are a good conductor.Alkali earth metals (Be, Mg, Ca, Sr, Ba, Ra): reactive but not as reactive as alkali metals.Alkali metals (Li, Na, K, Rb, Cs, Fr): extremely reactive and will burst into flame when contacting water.The members of these ten groups and their general characteristic in brief are: That means it will have a larger electron trajectory and therefore, a larger atomic radius. That is because the larger the element’s atomic number is, the more electrons it has. Meanwhile, the more above an element is in the periodic table, the larger its electronegativity is.įurthermore, the more right and above an element position is, the larger the atomic radius the element has. It will also be more nonmetal in nature and has more negative electron affinity. The more right an element location is in the periodic table, the larger ionization energy the element has. The relative position of one element to another in the periodic table of elements also has meanings. They also have similar physical properties and similar reactions to the elements in another group. The elements in the same group, on the other hand, have the same number of electrons in their outer shell. The number of orbitals ranges from 1 (which the elements in the top period have) to 7 (which elements in the bottom period have). The elements that are in the same period have the same number of orbitals. In the table, the elements are divided into periods (rows) and groups (columns). For example, as Nickel’s atomic number is 28 and Cobalt’s is 27, that means Nickel has more protons than Cobalt. The atomic number for each element (the number at the top of each element symbol in the table) represents the number of protons that element has. That is because we place the transition metals group there which nature is quite different from other elements. You may notice some gaps that the periodic table of elements has in the middle.

If you download the excel file of this periodic table of elements, you can edit the table display to your preference.īelow is the list of the chemical elements that have a place in the periodic table.Ī periodic table of elements places and groups the elements which existence we have identified based on their nature. Here is a snapshot of the periodic table of elements we have created for you.
