Which Group Tends To Form 1 Ions. Web ions made from alkaline earth metals, the second group on the periodic table, have a 2+ charge. They then have the same number of electrons as the nearest noble gas:

Web atoms of group 17 gain one electron and form anions with a 1− charge; Group 1 metals, the alkali metals, have the 1 valence electron, and thus form m + ions when oxidized. The halogens, group 17, reach a full valence shell upon reduction, and thus form x− ions. Web group ia elements form ions with a +1 charge. For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. Web atoms of group 17 gain one electron and form anions with a 1− charge; Rubidium (rb), cesium (cs), and francium (fr). Group 2 metals, the alkaline earth metals, have 2 valence electrons, and thus form m 2+ ions. Web consistent with a tendency to have the same number of electrons as the nearest noble gas, when forming ions, elements in groups 1, 2, and 3 tend to lose one, two, and three electrons, respectively, to form cations, such as na + and mg 2+. Web potassium, located directly beneath sodium in group 1, also forms +1 ions (k +) in its reactions, as do the remaining members of group 1:

Web group ia elements form ions with a +1 charge. The atoms of the elements toward the right end of the periodic table tend to undergo reactions such that they gain (or share) enough electrons to complete their. They then have the same number of electrons as the nearest noble gas: Web the 1st group (alkali metals) tends to form +1 ions. Atoms of group 16 gain two electrons and form ions with a 2− charge, and so on. Group 2 metals, the alkaline earth metals, have 2 valence electrons, and thus form m 2+ ions. Group 1 metals, the alkali metals, have the 1 valence electron, and thus form m + ions when oxidized. The halogens, group 17, reach a full valence shell upon reduction, and thus form x− ions. They lose one electron upon ionization, moving into the electron configuration of the previous noble gas. For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it.
