sodium
The common ion charge for the element Lithium (Li) is +1.
Potassium is a group 1 element, so it will form a 1+ ion.
No element on its own has a charge. However, in all of its compounds sodium forms a positive ion.
the cyanide ion has a single negative charge, CN-
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.
The common ion charge for the element Lithium (Li) is +1.
The element hydrogen forms an ion with the same charge as the ammonium ion, which is +1. When hydrogen loses an electron, it becomes a hydrogen ion with a +1 charge, just like the ammonium ion.
Potassium is a group 1 element, so it will form a 1+ ion.
Alkaline earth metals form cations withe the electrical charge +2.As an exceptional curiosity exist the ion Ca-.
No element on its own has a charge. However, in all of its compounds sodium forms a positive ion.
the cyanide ion has a single negative charge, CN-
All the listed elements form ions with a charge of 1, if "1" is taken as the absolute value of the charge on the ion. For fluorine, however, the corresponding ion has a charge of -1.
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.
The formula for the compound formed between lithium ion (Li+) and bromine ion (Br-) is LiBr. Lithium being a group 1 element with a +1 charge and bromine being a group 17 element with a -1 charge, they combine in a 1:1 ratio to form a stable ionic compound.
The usual ion form of fluorine is the fluoride ion, which has a charge of -1.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.
