True
Explanation:
In the crystal of an ionic compound, the cations are surrounded by anions so that the charges of the ions are balanced. This very correct.
Ionic compounds are electrically neutral and forms by a charge balance.
- To form an ionic crystal, the charges overall must be balanced and the compound must remain electrically neutral.
- Equal number of charges on the metal and non-metal must cancel out to establish an electrostatic force.

Answer: B
Oxygen acts as oxidator in the first reaction.
Explanation:
At reactant side:
Mg = 0
At product side:
MgO = 0
but Oxygen (O) = -2
Mg + O = 0
Mg + (-2) = 0
Mg - 2 = 0
Mg = 2
Magnesium is oxidized by OXYGEN from zero to +2
Oxygen acts as oxidator in the first reaction.
<span>spectroscopy,
</span><span>Some spectrometers work on things other than light. For example, a mass spectrometer takes a mixture of chemicals and separates them according to their weight. Other spectrometers measure invisible forms lof light like infrared or x-rays. The idea is always the same, though.
</span>Hope this helped!
