Periodic Properties Periodic Properties Of Elements Their Functions 1 periodic properties of the elements. early versions of the periodic table were constructed by mendeleev and meyer. we now know that the periodic properties are due to the electronic structure of atoms. electronic structure explains the observed trends in atomic size ionization energy electron affinity al zn ga cd in sn. Groups 1 and 2 and 13–18 are called the main group or representative elements. the elements in groups 3–12 are called the transition elements. 3 main classes. elements are divided into three main classes—metals, metalloids, and nonmetals. as you can see from the periodic table, the majority of the elements are metals.

The Periodic Table History Of The Periodic Table Ch. 14.1 classification of the elements. the periodic table is one of the most important tools in chemistry. elements are arranged according to atomic number, but the periodic table also relates to atomic structure and trends among the elements. elements can be classified into 4 categories according to their electron configurations. Periodic trend nonmetals tend to gain electrons. the size of the atom becomes larger with the addition of each consecutive electron. the nuclear charge has less of a pull on the electrons with the gain of each electron due to greater electron repulsion! download ppt "periodic properties of elements". In a many electron. atom, electrons are both attracted to the nucleus and repelled by other electrons. the nuclear charge that an electron experiences depends on both factors. effective nuclear charge. the effective nuclear charge, way: zeff, is found this. zeff = z − s where z is the atomic number and s is a screening constant, usually close. 19 group (family) properties eighteen groups on the periodic table (numbered from left to right) atomic numbers and atomic masses increase as you move from the top down in a group (family) atoms of elements in the same group have the same number of electrons in the outer orbitals levels of their atoms (known as valence electrons) exceptions: transition elements (3 12) hydrogen (could be 1 or.

Properties of the periodic table. the periodic table vertical columns are called groups groups are numbered from 1 to 18. the periodic table • valence electrons are electrons located on the outermost energy level. • each element in a group has the same number of valence electrons. each row is called a period each period starts with an atom. 2. the periodic table is divided into blocks based on orbital types. elements show trends in properties within periods and down groups, including decreasing atomic radius and increasing ionization energy with increasing atomic number. electron affinity also tends to decrease down groups. 3. successive ionization energies increase as more energy.
