Question

Write the symbol for each of the following ions:

a) Sodium ion: _________

b) Chloride ion: _________

c) Magnesium ion: _________

d) Oxide ion: _________

Answer 1

The symbols for the ions are Na+ for the sodium ion, Cl- for the chloride ion, Mg2+ for the magnesium ion, and O2- for the oxide ion, with the superscripts indicating their respective charges.

Step-by-step explanation:

The symbols for the ions you have asked for are as follows:

a) Sodium ion: Na+

b) Chloride ion: Cl−

c) Magnesium ion: Mg2+

d) Oxide ion: O2−

Each ion symbol includes the element's symbol from the periodic table followed by a superscript that indicates the charge of the ion. A positive sign indicates a cation (an ion that has lost electrons), while a negative sign indicates an anion (an ion that has gained electrons).
