Which Group Tends To Form 1 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+. The general outer electronic configuration of alkali metals are ns1,np0 if they lose one electron,it will attain stable electronic configuration.

For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. The halogens, group 17, reach a full valence shell upon reduction, and thus form x− ions. For example ,lets take sodium (na. Group 1 metals, the alkali metals, have the 1 valence electron, and thus form m + ions when oxidized. Web atoms of group 17 gain one electron and form anions with a 1− charge; That is, group 1 elements form 1+ ions; Web atoms of group 17 gain one electron and form anions 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. Web group ia elements form ions with a +1 charge. They lose one electron upon ionization, moving into the electron configuration of the previous noble gas.
Web ions made from alkaline earth metals, the second group on the periodic table, have a 2+ charge. That is, group 1 elements form 1+ ions; The halogens, group 17, reach a full valence shell upon reduction, and thus form x− ions. 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: Group 2 metals, the alkaline earth metals, have 2 valence electrons, and thus form m 2+ ions. They then have the same number of electrons as the nearest noble gas: Web ions made from alkaline earth metals, the second group on the periodic table, have a 2+ charge. Web the 1st group (alkali metals) tends to form +1 ions. For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it. Atoms of group 16 gain two electrons and form ions with a 2− charge, and so on. Atoms of group 16 gain two electrons and form ions with a 2− charge, and so on.
