Going across the Periodic Table from left to right ignoring the transition metals, +1 charge are for group IA, group IIA is for +2 then it skips to group IIIB with +3 charge, group VB is -3, group VIB is -2, group VIIB is -1 charge.
Elements in a periodic table are arranged in order of atomic number, usually in rows, so that elements with similar atomic structure and hence similar chemical properties appear in vertical columns.
Elements are arranged on the Periodic Table by their relationships with other elements.
Every element in a period (row) has the same amount of electron shells.
Every element in a group (column) has the same amount of electrons in the outer shell.
Groups also share physical characteristics, such as Group I all reacting a lot with water.
Examples.
Period 1.
Hydrogen 1.
Helium 2.
Group 1.
Lithium 2. 1.
Sodium 2.8.1.
Potassium 2.8.8.1
Rubidium 2.8.18.8.1
Caesium 2.8.18.18.8.1
Francium 2.8.18.32.18.8.1
A cation is a postively-charged ion; cations are not normally found on the periodic table but the alkali metals and the alkaline earth metals typically become cations. In metallic bonding, the delocalisation of the outer electrons means that metal cations are in a lattice of electrons.
Cations are not listed in the periodic table because they are a variant of an element! A few examples: K+ is not listed because K is. PF6- is not listed because it is a compound.
Cations are positively charged ions. In general, elements on the left hand side of the table make positively charged ions in ionic compounds.
The elements of the periodic table are arranged by their number of protons. The number of protons is also the atomic number of the element.
Periodic table lists elements not cations. However the elements on the left side of the periodic table are metals and are likely to form cations.
All atoms are in the periodic table are arranged by their atom number, which is by definition equal to the number of protons in their nucleus.
In lattices where each anion has cations as its nearest neighbours and each cation has anions as its nearest neighbours
a group that forms anions with a -1 charge
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
Usually it is unsoluable, but it is soluable with Fe3+, NH4+ and the group 1 in the periodic table (these cations, except for Fe3+, make all anions soluable).
Anions are negatively charged atoms.Non metals gain electrons to form anions. They are placed on right side in the periodic table.
Mendeleev's periodic table was arranged in order of increasing atomic mass.Modern periodic table is arranged in order of increasing atomic number.

A displacement table would be used to find information on which cations or anions will replace other cations or anions in a chemical reaction.
Cations are positively charged ions. Metals form cations.They are present on left side in periodic table.
A tool that would be used to find information on which cations or anions will replace others in a chemical reaction is a displacement table.

In the periodic table, the elements are arranged by atomic number
Usually it is unsoluable, but it is soluable with Fe3+, NH4+ and the group 1 in the periodic table (these cations, except for Fe3+, make all anions soluable).
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
elements which have 1 to 3 valence electrons will generally lose electrons and form cations. elements which need 1 to 3 electrons to attain the nearest noble gas configuration will generally gain electrons and form anions
Periodic table was initially arranged by Mendeleev. It was rearranged by Moseley.
