Which element forms 2 or more ions with different ionic charges?
A few elements, all metals, can form more than one possible charge. For example, iron (Fe) atoms can form 2+ cations or 3+ cations. Cobalt (Co) is another element that can form more than one possible charged ion (2+ and 3+), while lead (Pb) can form 2+ or 4+ cations.
Which of the following elements forms two or more ions with different ionic changes?
The correct answer is iron (Fe).
What elements will form 2 ions?
The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions. The calcogens (green) form -2 ions. Many of the transition metals (orange) can have more than one charge.
Which element has 2+ charge when it forms ion?
A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+. The symbol for the ion is Mg2+, and it is called a magnesium ion.
Which element can form ions with different charges?
A few elements, all metals, can form more than one possible charge. For example, iron (Fe) atoms can form 2+ cations or 3+ cations. Cobalt (Co) is another element that can form more than one possible charged ion (2+ and 3+), while lead (Pb) can form 2+ or 4+ cations.
What element forms 2+ ions?
The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions. The calcogens (green) form -2 ions. Many of the transition metals (orange) can have more than one charge.
Which elements tend to form ions with a 2 charge?
The alkali earth metals (group 2), such as, Mg or Sr lose two e-‘s to attain the configuration of Ne. Thus, the group 2 metals tend to have a +2 charge. On the other side of the periodic table elements gain electrons to resemble the next higher noble gas.
Which group has a 2+ ionic charge?
alkaline earths
What elements can form ions with different charges?
The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions. The calcogens (green) form -2 ions. Many of the transition metals (orange) can have more than one charge.
What metals form multiple ions?
A few elements, all metals, can form more than one possible charge. For example, iron (Fe) atoms can form 2+ cations or 3+ cations. Cobalt (Co) is another element that can form more than one possible charged ion (2+ and 3+), while lead (Pb) can form 2+ or 4+ cations.

What element is most likely to form a 2 ion?
(a) Zinc is the most likely to form a +2 ion. An atom must lose or transfer its valence electrons to form an ion with a complete octet or stable
What elements gain 2 electrons to form an ion?
For example, oxygen atoms gain two electrons to form O2- ions. These have the same electron configuration as the noble gas neon.
Which group of elements forms ions with a 2+ charge?
Ions made from alkaline earth metals, the second group on the periodic table, have a 2+ charge.
