Explain Why?
1. An oxide ion O ? has -2 charge.
2. Magnesium ion, Mga has +2 charge
3. Sulphide ion, s'has -2 charge,
Answers
Answer:
The ion has the same number of protons because you never lose a proton to make an ion. But in the case of oxide form, it carries two negative charges.
Explanation: Magnesium is under group 2 that also has a valence electron of 2. To achieve stability and to follow the octet rule, these 2 electrons in the outer shell will be removed making this atom into an ion with a 2+ charge. ... Thus, magnesium has the ionic symbol of Mg2+ .
Anions are designated by their elemental name being altered to end in “-ide”: the anion of chlorine is called chloride, and the anion of sulfur is called sulfide, for example. ... Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge.
