What are the ions in Group 1?
Group 1 metals, the alkali metals, have the 1 valence electron, and thus form M+ ions when oxidized. Group 2 metals, the alkaline earth metals, have 2 valence electrons, and thus form M2+ ions. The halogens, Group 17 , reach a full valence shell upon reduction, and thus form X− ions.
Why does group 1A have a 1+ charge?
The alkali metals will lose an electron to resemble the next lowest noble gas; thus, all the alkali metals form +1 ions. K loses an electron so that it will have the same electron configuration as Ne. Since K loses one electron (1 negative charge) it is no longer neutral; it now has a +1 charge.
What is a +1 ion?
When a neutral atom loses an electron, the number of charges in the protons and electrons are no longer equal; the positive charge of the protons wins out and the atom becomes an ion with a net charge of +1.

Why do Group 1 metals form +1 ions?
Key Concepts and Summary. Metals (particularly those in groups 1 and 2) tend to lose the number of electrons that would leave them with the same number of electrons as in the preceding noble gas in the periodic table. By this means, a positively charged ion is formed.
Which elements form ions with a 1+ charge?
Charges on ions The alkali metals (shown in yellow) always form +1 ions. The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions.
How many ions does Group 1 have?
1+ ions
That is, group 1 elements form 1+ ions; group 2 elements form 2+ ions, and so on. Moving from the far right to the left on the periodic table, elements often form anions with a negative charge equal to the number of groups moved left from the noble gases.
Which group typically forms ions with a 1 charge?
The alkali metals (shown in yellow) always form +1 ions. The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions.
What is the charge of an ion?
Since the electric charge on a proton is equal in magnitude to the charge on an electron, the net electric charge on an ion is equal to the number of protons in the ion minus the number of electrons.
Why does silver form a 1+ ion?
Silver (symbol: Ag) is a metal and has only 1 ion ( ), which is formed when the silver atom loses 1 electron. Metals generally have a tendency to lose one or more electrons, and this results in the formation of metal cations. Silver also forms a cation ( ).
What charge will atoms in Group 1 take on?
+1 charge
Group I (alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge. Metal ions may have other charges or oxidation states. For example, copper usually has a +1 or +2 valence, while iron typically has a +2 or +3 oxidation state.
Why do sodium ions have a 1+ charge?
A sodium atom has one electron in its outer shell. A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1.
What kind of charge does Group I have?
Group I ( alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII ( noble gases) carry a 0 charge. Metal ions may have other charges or oxidation states.
Which is an example of an ionic charge?
Metal ions may have other charges or oxidation states. For example, copper usually has a +1 or +2 valence, while iron typically has a +2 or +3 oxidation state. The rare earths often carry many different ionic charges.
What kind of charge does an alkali metal have?
Group I (alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge. Metal ions may have other charges or oxidation states. For example, copper usually has a +1 or +2 valence, while iron typically has a +2 or +3 oxidation state.
What happens when lithium is added to Group 1A?
The reaction becomes more vigorous as one moves from top to bottom in Group 1A: lithium sizzles fiercely in water, a small amount of sodium reacts even more vigorously, and even a small amount of potassium metal reacts violently and usually ignites the hydrogen gas; rubidium and cesium explode.
