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.

∙ 10y agoThe defining characteristic of metals and nonmetals is that metals have a much lower electron affinity than nonmetals do. Metals tend to lose electrons when they undergo a chemical reaction, while nonmetals tend to gain electrons when they undergo a chemical reaction.

How does metallic character relate to first ionization energies?
we know that metal has tendency to lose a electron more easily than non metals so the value of the first ionization energy of the metals is very small.
Are alkalai metals metal?
According to the scientific definition of a metal yes, Alkali metals are considered metals, but it is important to understand that alkali metals have different properties from regular metals. The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound. This gives them the largest atomic radii of the elements in their respective periods. Their low ionization energies result in their metallic properties and high reactivities. An alkali metal can easily lose its valence electron to form the univalent cation. Alkali metals have low electronegativities. They react readily with nonmetals, particularly halogens.
How is the reactivity of metals related to the periodic table?
In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive nucleus and negatively charged outer electron. (All Group 1 elements have 1 electron in their outer shell). Also, because they contain more shells down the group, the distance between the nucleus and electrons is increased. Therefore the electrostatic force is lessened between them. Both of these allow the outer electron to be lost easier to other elements, thus increasing reactivity.
Why two non-metals can combine to form a compound but two metals cannot?
Two metals can not form a compound like two non metals can because of alloys, or is it cations or anions. I think this is the answer i took chemistry 3 years ago sorry if this is not right.
What is ionization suppressor?
An ionization suppressor is a salt of an alkali metal added to suppress ionization of an analyte. The alkali metal is easily ionized resulting in a flux of electrons which shift the ionization equilibrium of analyte towards formation of atoms.

Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
Why do the alkali metal have lower ionization energies than the alkaline earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
Sodium an alkali metal and chlorine a halogen are both in Period 3 of the periodic table Which element has a higher ionization energy?
Chlorine has a higher ionization energy. Chlorine's tendency is to gain electrons, not lose them as metals usually do.
What physical properties do metalloids have?
They are half metal and half nonmetal. some examples areBoronSiliconGermaniumArsenicAntimonyTelluriumPoloniumI belive that metaloids are also called semiconductors. ENJOY!
Chemical properties of metal?
•They have low ionization energies •Tend to form complexes •Good conductors of heat and electricity
Why does copper conduct heat faster then steel or brass?
Copper's conductivity properties are based on its electronegativity. Generally, all metals must have low electronegativity and ionization energies. But all metals do not have the same electronegativity levels.
Do the elements form anion have high or loe ionization energy?
low ionization energy

Is apoor conduct of electricity an metal or non metal?
a poor conductor of electricity is never a metal because metals have low ionization enthalpies and thus electrons can be easily mobilized.
Why alkaline metals not exist naturally in free state?
Akaline metal do not exist in free state due to high level of ionization energy in them.
What method is used to extract metals that are above carbon in the reactivity series?
Usually they put electricity into the metal ion solution to reverse the ionization
