- fluorine is the most electronegative of the elements
- caesium is the least electronegative
Source: The widely quoted Pauling electronegativity of 0.7 for francium is an extrapolated value of uncertain provenance. The Allen electronegativity of caesium is 0.66.

What is the noble gas configuration for element 117?
Based on the trends in the periodic table, the noble gas notation of the element with atomic number 117 will be[Rn]5f146d107s27p5
What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads
What periodic trends did Mendeleev organize his periodic table by Atomic number Atomic mass Octaves Triads First ionization energy?
In 1869, Mendeleev organized his periodic table by increasing atomic mass (atomic weight), using what is called the "law of octaves," by which every 8th element in the sequence shared similar properties. This was first observed by John Newlands in his element table around 1863.
How can you predict the placement of an unknown element on a periodic table based on physical an chemical properties?
You look at trends. An element is likely to have properties somewhere between the element above it and the element below it; if there's nothing below it (or above it), then you can follow the general trend up (or down) that column and extrapolate.
What periodic trends of reactivity occur with the alkali metals?
Reactivity increases the farther down you go in the Periodic Table.
How are the trends in the periodic table helpful in identifying an element?
The periodic trends that arise from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or period and the periodic nature of the elements.
Why is sodium the eleventh element?
Because it has 11 valence electrons Please see : Trends in the periodic table
What are 2 reasons for studying the periodic table?
Periodic table of elements provides us a lot of information about element's intrinsic properties. We can get the atomic weight of an element by looking at the periodic table. Trends about the electronegativity and atomic size can also be computed.
What is the noble gas configuration for element 117?
Based on the trends in the periodic table, the noble gas notation of the element with atomic number 117 will be[Rn]5f146d107s27p5
How do periodic trends affect bonding?
Periodic trends affect bonding due to the arrangement of the elements on the periodic table. The periodic table only includes chemical elements.
What are the names of the trends in the periodic chart?
No
What did organizing information on the periodic table reveal?
Periodic patterns and trends
How do periodic trends illustrate and change in chemistry?
Periodic trends illustrate how some elements are very reactive while others are stable.
What are names of the trends in the periodic chart?
Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.
The periodic table is called periodic because the?
in 1869 periodic trends in the properties of the then-known elements
Which 3 atomic properties will you examine for periodic trends?
For periodic trends we will examine1- Electronic configuration 2- Ionization energy 3- Atomic radius
How you can know that which element is mor reactive?
It depends on the placing of the element in the periodic table. For the far left, group 1, the most reactive element is the one closest to the bottom. For the far right, the most reactive is the one closest to the top. The table follows certain trends, depending on it's placement in the periodic table. By learning these trends, you'll be able to tell at a glance. For example, Francium, the bottom-left most element only ever exists for a fraction of a second; it's so reactive, it reacts when it is created.
