How are elements that form positive ions grouped in the periodic table relative to elements that form negative ions?
The lower the the Atomic Number, the higher the Ionic Energy.
How were the elements in the periodic table arranged?
By Atomic Mass
Why the relative atomic numbers of some elements are not shown in the periodic table?
All known elements are listed on the periodic table of the elements. Historical tables did not have elements listed that were unknown at the time. For instance, Dimitri Mendeleev, who laid out the first successful periodic table in 1869, did not have any of the noble gases listed since none of them had been discovered at that time. Modern periodic tables have gaps at the lower right end where elements are expected to be created in labs in the future, but have not been successfully created yet.
What three things can each square in the periodic table tell you besides the name of the elements?
*Symbol*Atomic number *Relative atomic mass
Do the relative positions of there elements in the periodic table with the prediction made in the introduction about their strut re?
The relative positions of elements in the periodic table correlate with their predicted structures based on periodic trends such as atomic size, electronegativity, and valence electron configuration. Elements in the same group typically exhibit similar bonding characteristics and structural properties due to having the same number of valence electrons. For instance, metals tend to form crystalline structures, while nonmetals may exhibit molecular or network structures. Thus, the predictions made about their structures align with their positions in the periodic table.

How is the relative atomic mass calculated for elements on the periodic table?
The relative atomic mass of an element is calculated by taking the weighted average of the masses of its isotopes, based on their abundance in nature. This value is listed on the periodic table below the element's symbol.

How were the elements arranged on his periodic table?
The elements on the periodic table are arranged in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement helps group elements with similar properties together in columns called groups or families. Additionally, elements are organized into rows called periods based on their electron configurations.

Define the periodic table of elements?
The periodic table of elements arranges elements in order of Atomic Number, Reactivity and Relative Atomic Mass. The columns are called 'Groups' the rows called Periods. It mostly contains metals on the left side and non-metals on the right. There are basically 8 groups of elements that as you go down the group the element becomes more reactive.
What did dimetri mendeleev find out about the periodic table?
Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today.
What does electronegativity means in the periodic table?
Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. It increases across a period from left to right and decreases down a group in the periodic table. Elements with high electronegativity tend to form negative ions, while elements with low electronegativity tend to form positive ions in chemical compounds.
How can an elements propertes be predicted?
An element's properties can be predicted based on its position in the periodic table, which is organized by increasing atomic number and similar chemical behavior. Elements with similar properties tend to be grouped together in columns, called groups, and rows, called periods. The arrangement of elements in the periodic table allows scientists to make predictions about an element's properties based on its location relative to other elements.
Why do some elements not have relative atomic masses eg. radium?
All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the atomic mass of the most stable isotope.The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
