Non metals have high ionisation energies, since they tend to gain electrons. They have more electrons in the valence shell compared to metals, therefore more energy is required to remove them. They also have more protons, which is essentially the pulling power, therefore the electrons are closer and more energy is required to remove them.

∙ 14y agoIn general, electronegativity values decrease from top to bottom within a group. For representative elements, the values tend to increase from left to right across a period. Metals at the far left of the Periodic Table how low values. By contrast, nonmentals at the far tight (excluding noble gases) have high values.

∙ 15y agoThis is not necessarily true. Polymers often has lower melting points than metals.
The melting of materials depends on many factors including molecular bond type (covalent, ironic, metallic) and purity of the material.

∙ 9y agoThis is because ionization energy values for the elements rise as we move across the periodic table, and nonmetals are located to the far right. As we move down a group, metals become more reactive.

∙ 9y agoNonmetals have higher ionization energy than metals because they need to add electrons. Unlike metals that are trying to lose electrons, they need more energy to gain them.

Why do non metals have higher ionization energies than metal?
Ionization energy is the energy needed to remove an electron. Elements other than transition metals gain or lose electrons from the s and p orbitals in order gain the more stable electron configuration of a Noble gas. Metals lose electrons to become isoelectronic (that is have the same electron configuration) to a noble gas (previous to them in the periodic table), while nonmetals tend to gain electrons in order to become isoelectronic to a Noble gas (next highest on the periodic table). Since ionization energy is the energy needed to REMOVE an electron, it is low for metals which form positive ions by losing electrons to become more stable, but very high for nonmetals that tend to gain, NOT LOSE, electrons. Most transition metals tend to lose electrons as well (other than Rhenium). Transition metals lose electrons from the d orbital, but still form positive ions, so their ionization energy is also usually lower than nonmetals.
Do nonmetals have a low first ionization energy?
No. Nonmetals have a high first ionization energy.
What are the properties of a nonmetal?
Nonmetals have high ionization energies and electro negativities. They are generally poor conductors of heat and electricity.Solid nonmetals are generally brittle, with little or no metallic luster.Most nonmetals have the ability to gain electrons easily.Nonmetals display a wide range of chemical properties and reactivities.
Both Groups IA and IIA have what ionization?
They both have alkaline ionization energies.
Ionization energies of oxygen and xenon same or not?
No, but they are similar.
Would you expect metals or nonmetals in the same periods to have higher ionization energies?
Non-metals have higher ionization energies within the same period. This is because non-metals want to gain electrons to be able to be like the nearest noble gas.
Why are nonmetals more likely to react with each other by sharing electron?
nonmetals have relativly high ionization energies. Nonmetals have relatively high ionization energies .
