Here's what I get
Explanation:
At the introductory level of chemistry, I can think of only two situations when you use Greek prefixes.
They indicate the number of atoms or groups in a molecule when you are naming a compound.
1. Binary covalent compounds
For example, P₂S₅ is diphosphorus pentasulfide.
2. Hydrates
For example, Na₂SO₄·10H₂O is sodium sulfate decahydrate.
Answer:
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.
Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
Explanation:
<h3>Answer:</h3>
Ionic Bond
<h3>Explanation:</h3>
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bonding
Between 0.4 and 1.7 then it is Polar Covalent Bonding
Greater than 1.7 then it is Ionic Bonding
For Mg and Cl,
E.N of Chlorine = 3.16
E.N of Magnesium = 1.31
________
E.N Difference 1.85 (Ionic Bond)
<h3>Conclusion:</h3>
MgCl₂ being ionic in nature when dissolved in water dissociates into Magnesium and Chloride ions respectively.
