Helium has the highest ionization energy (IE) among all the elements, as it has a fully stable electron configuration that resists losing an electron. Other elements with high ionization energies include neon, followed by elements in the noble gas group due to their stable electronic configuration.
Elements with the highest atomic mass can be found towards the bottom of the periodic table, typically in the bottom rows known as the actinide and lanthanide series. These elements include heavy elements such as uranium, thorium, and plutonium.
To determine which element has the highest electronegativity, we typically refer to the Pauling scale. Among common elements, fluorine is assigned the highest electronegativity value of 3.98. This is due to its small atomic size and high effective nuclear charge, which allows it to attract electrons more strongly than other elements.
Helium has the highest ionization energy.
The elements with the highest ionization enthalpy are helium, neon, and argon. These noble gases have full valence electron shells and are very stable, making it difficult to remove an electron from them.
The element with the highest ionization energy in Group 3A (Group 13) is usually thallium (Tl), followed by indium (In) and then gallium (Ga). Thallium has the highest ionization energy due to its partially filled d-orbital, which imparts extra stability.
Fluorine has the highest electronegativity.
Silver has the highest conductivity among all known elements.
ammonia have only two elements ie: nitrogen and 3 hydrogens as per me
names of the five elements with the highist densities
flourine
Iridium is the elemento with the highest density
Elements with the highest atomic mass can be found towards the bottom of the periodic table, typically in the bottom rows known as the actinide and lanthanide series. These elements include heavy elements such as uranium, thorium, and plutonium.
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.
Fluorine has the highest electronegativity value of all elements.
Tungsten has the highest boiling point among all known elements and compounds.
Nitrogen has the highest electronegativity.
Osmium and iridium are the two elements with highest density.
