Use ionization energy to explain why metals lose electrons more easily than nonmetals?
Metals lose electrons more easily than the non-metals because they require less ionization energy compared with the non-metals. The metals require less ionization energy to lose the electrons than though gain the electrons unlike the non-metals.
Why are valence electrons easier to remove from an atom than core electrons?
Valence electrons are further away from the nucleus and experience less attraction to the positively charged protons in the nucleus compared to core electrons. This makes valence electrons easier to remove from an atom. Core electrons are located closer to the nucleus and are more strongly attracted to the nucleus, requiring more energy to remove them from the atom.
Do metals more readily gain or lose electron?
Metals more readily lose electrons to form positive ions. This is because metals have a few valence electrons and a low ionization energy, making it easier for them to lose electrons and achieve a stable electron configuration.
Do metals or nonmetals tend to gain electrons more easily?
nonmetals are located in the right side of the periodic table. The Ionization energy(the amount of energy used to remove an electron) tends to increase from left to right across a period.It is difficult to remove the electrons from the right side because they are becoming stable
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.

Is aluminum a conductivity?
Yes due to the fact it is a metal and metals have delocalised (free) electrons which allow the electrons to move around the metal conducting heat and electricity easier than non metals
Why do metals tend to lose electrons form positive ions?
Metals tend to lose electrons to form positive ions because, for metals to gain a full outer shell, they need to lose electrons.

Why only 12 elements form ions easier than the rest of the elements in periodic table?
I would imagine that these elements are hydrogen, the alkali metals and the halogens. Hydrogen and the alkali metals only have one outer electron, which is easier to displace than the two outer electrons of the alkaline earth metals, for example. In contrast, the halogens only need one more electron to have a complete outer shell; it is easier to accept one electron than the two electrons needed by the chalcogens - oxygen, sulphur, selenium etc.
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It all has to due with ionization energy. Ionization energy is the energy required to remove an electron from an atom to make it an ion. Cesium has a lower ionization energy than Lithium, so it is easier to remove electrons, and thus lose electrons, from a Cesium atom than a Lithium atom.
Explain why alkali metals have a greater affinity for electrons than alkaline earth metals?
They don't, they actually have a greater tendency to lose electrons. This is for a number of reasons. First of all, the alkali metals form a stable cation by losing one electron, while the alkaline-earth metals need to lose two to form a stable ion. It takes more energy to remove one electron from an atom than it does to remove two. Additionally an alkaline earth metal has a greater positive charge on its nucleus and a smaller atomic radius than an alkali metal in the same row of the periodic table. This make it even harder to remove valence electrons. ------------ ?? WRONG: Alkali metals have a valence electron configuration of ns1 so they can accept another electron in the ns orbital. On the other hand, alkaline earth metals have a valence electron configuration of ns2. Alkaline earth metals have little tendency to accept another electron, as it woudl have to go into a higher energy p orbital.
Why it is so much easier to remove an elcetron from an atom of large atomic weight thabn it is to remove proton?
electrons orbit the nucleus so they come "loose" easier than the protons, which are held in place by a thing called "strong force". strong force is greater than the force holding an electron in orbit around the nucleus.
Would you expect nonmetals to have larger electron affinities than metals?
Yes. Non metals have larger electron affinity than metals as non metals accept electrons more easily than metals.
