The most common way to determine the ion of an atom on the Periodic Table is to look at the group it is in. Moving from left to right the elements will usually have the ionic charges of +1,+2,+3,+-4,-3,-2,-1. All elements in each group will have the same ionic charge . The transition metals are not as easy as this but a general method to use is that most transition metals have a charge of +2. This iosnt true for all of them but if you are not sure on their charge it is bsest to go with +2. Otherwise the other method i have said is a good way to determine the ion that will form
they are grouped by the number of valence electrons.
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
Predicting if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table involves comparing their electronegativities. If the electronegativities of the atoms are similar, the bond is nonpolar. If there is a significant electronegativity difference between the atoms, the bond is polar.
Periodic trends are patterns that are observed as you move across or down the periodic table of elements. These trends include atomic radius, ionization energy, electronegativity, and metallic character, among others. They help predict the properties of elements based on their position in the periodic table.
They use a Periodic Table.

The elements in the Periodic Table are arranged so that elements in the same group (column) will exhibit certain similar characteristics with others in that same group, but different periods (rows). So you can predict, with a certain degree of confidence, how a certain element may behave by where it is located on the periodic table, based on what you know about how other elements in the same group behave. This is mainly due to the valence electrons (the outermost electrons) being the same configuration as others in the same group. The valence electrons are a big determining factor as how that element will react with other elements. They do not all behave exactly the same, but similar.
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).
they are grouped by the number of valence electrons.
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.
I think the elements with more number of shells and least number of electrons in the outer most shell would be the one. For example francium.
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
We can predict the electron configuration, some chemical and physical properties, the atomic weight, etc.
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
