This location indicate that francium is an alkali metal, very reactive.
They all are molecules.
Periodic table describes chemical properties of element.It can also describe its degree of reactivity.
It can tell you crtain characteristics of that element.
By number of elctrons,protons in them and their reaction rate
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
Electronegativity increases while moving left to right along the period and decreases down the group in the periodic table.
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.
Tells you where this element resides in the period table. tell you which group,,metallic , gas, or liquid.
tell table of 2
how to tell if a table s proportional or non proportional
please, tell me the dimensions of the table and than i am able to tell the area of the table. parveen mor, ISBS,PUNE
The rows (periods) work out to be the energy levels, ex. if an element is in period 5, it has 5 energy levels.
