What element has 12 protons and 10 electrons?
Understand the Problem
The question is asking for the identity of a chemical element based on its number of protons and electrons. Generally, the number of protons in an atom defines the element, and the number of electrons indicates its charge. Here, with 12 protons, we are looking for the element magnesium, which typically has 12 electrons, but here it has 10 which means it has a +2 charge.
Answer
magnesium ion (Mg²⁺)
The final answer is a magnesium ion (Mg²⁺)
Answer for screen readers
The final answer is a magnesium ion (Mg²⁺)
More Information
A magnesium ion (Mg²⁺) is formed when a magnesium atom loses two electrons, resulting in 12 protons and 10 electrons.
Tips
A common mistake is confusing the number of protons or electrons for another element, but the atomic number uniquely identifies magnesium.
