sodium and lithium are both in group 1
Chlorine always forms ions of charge -1. However in its compounds, it also shows oxidation states of +1,+3,+5 and +7.
Because sodium loss only one electron from the outer electron shell and become a cation with the charge +1.
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
-1
Sodium ions have a charge of 1+
AlCl3
sodium and lithium are both in group 1
The halogen (group 17/VIIA) atoms form ions with a 1- charge when undergoing ionic bonding. An atom gains one electron from a metallic element, resulting in the metal developing an ion with a 1+ charge. The electrostatic attraction between the oppositely charged ions forms the ionic bond.
Chlorine always forms ions of charge -1. However in its compounds, it also shows oxidation states of +1,+3,+5 and +7.
Because sodium loss only one electron from the outer electron shell and become a cation with the charge +1.
When group 1A elements form ions, they form cations with a +1 charge.
Iodide is monovalent anion. It is I+The charge of the iodide ion is 1-
Lead lose two electrons and silver lose one electron.
1 because Na ions have a +1 charge while Cl ions have a -1 charge.
Alkali metals are found in group 1 of the periodic table. They will form ions with a 1+ charge. If you meant alkaline earth, they are found in group 2, and will form ions with a 2+ charge.
Atoms with charge are called ions. These ions have either gained or lost valence electrons to gain a net positive or net negative charge. Ions with a positive electrical charge of positive 1 (+1) are metals in the Alkali Metals Group and Hydrogen. Ions with a negative electrical charge of 1 (-1) are elements in the Halogen Group.
