Answer:
The main reason why some stable ionic compounds have +1 charged ions, even though other higher would have a more favorable lattice energy is because;
1. Energy is required to remove each of the electrons in an atom, and the more more the electrons are removed, the smaller the atom radius becomes, with increasing nuclear attraction between the opposite charges.
Note, it is a bit easy to remove a single electron, when compared to 4, 5 or 6 electrons. hence, the reason why Ionic compounds are more stable with + charged ions than others.
2. The stability of an ionic compound is dependent on his lattice energy. And the ions with large charge will have a greater attraction between the cations and anions, hence have higher lattice energy. However, the distance between the ions and the nucleus of the atom plays a major role in the stability of the ion.

Answer:
C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.
The unbalanced reaction:
I₂ + O₂ -----> I₄O₉
<u>Reactants</u>: 2 iodine, 2 oxygen
<u>Products</u>: 4 iodine, 9 oxygen
The balanced equation:
4 I₂ + 9 O₂ -----> 2 I₄O₉
Reactants: 8 iodine, 18 oxygen
Products: 8 iodine, 18 oxygen
Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.
Answer:
Bendable
Explanation:
An object/item that is able to bend/extend by being beaten with a hammer/object. This makes an object easier to make other things with.
Answer:
Ionic bonds transfer ions while covalent bonds equally share them.
Explanation:
In an ionic bond, ions are transferred between each other and ionic bonds form between a metal and nonmetal.
Covalent bonds are equally shared between atoms and form between non metals only.
Specifically, nonpolar covalent bonds are perfectly symmetrical with equal distribution of electrons while polar covalent bonds are asymmetrical and there is a difference in electronegativity.
