What do elements in a group have the same?
The position of an atom/element in the periodic table is related to the number of electrons in the outermost shell. In a given column or group, all elements have the same number of electrons in their outermost shells. For example, in group 2, all elements have two electrons in their outermost shell.

What properties do elements in a group or family have?
Elements of the same family show similar characteristics such as chemical re-activity or the same number of valence electrons. . - Electronegativity and ionization energy increase across a period and up the group

What does each element in the same group have?
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.

What are group elements called?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same core charge), because ...

De nition 4: We denote by jGjthe size of a group G, and call this the order of G. The word order means something slightly di erent when used with particular group elements: the order of an element g2G, written o(g), is de ned to be the smallest natural number such that gn = e, if such an nexists. If not, we say ghas in nite order.

example, in the group of all roots of unity in C each element has nite order. Theorem3.2gives a nice combinatorial interpretation of the order of g, when it is nite: the order of gis the size of the group hgi. In fact, this even works when ghas in nite order (then hgiis an in nite group), so the order of gis always the size of hgi.

so D3 is isomorphic to the group S3 of permutations of three objects. J Rather than constructing a group multiplication table it is often easier to construct group elements using a smaller number of generators of the group. • For D3 one can use two generators rand a, and write the other elements in terms of them: e= r3 = a2; s= r2; b= ar; c ...
