The element with the highest electro negativity is Fluorine. The general trend on the Periodic Table for electro negativity is that as you go across periods (horizontally) the electro negativity increases while going down groups (vertically) the electro negativity decreases.
Which ion has the same electronic configuration as argon
Non-metals
The elements with the highest mass are on the bottom right of the periodic table.
Boron has the highest ionisation potential among group IIIA elements.
Helium
hi
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
clorine clorine
The elements with the highest mass are on the bottom right of the periodic table.
Fluorine has the highest electronegativity.
Boron has the highest ionisation potential among group IIIA elements.
flourine
Iridium is the elemento with the highest density
Group 17 elements have the highest electronegativity out of which fluorine has the highest electronegativity.
names of the five elements with the highist densities
Carbon (C) has the highest melting point out of all the elements, and so, as it's in the first 20 elements, it has the highest melting point of the first 20 elements too. Its melting point is 3823K.
Nitrogen has the highest electronegativity.
Osmium and iridium are the two elements with highest density.
Electronegativity and first ionization energy both increase as you move up the periodic table
