Answer:
Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. These compounds are brittle and break into small pieces easily.
Explanation:
Which physical property can be measured? color density odor shape
The physical property that can be measured is the density. Color, odor and shape are properties that cannot be measured. They can be only observed through the naked eye and is subject to qualitative measurement.
Answer:
b) I took the test
Explanation:
2. Silver
3. Copper
4. Sulfur
Potassium is the element that is so active chemically that it occurs naturally only in compounds.
The element that is so active chemically that it occurs naturally only in compounds is potassium.
Potassium is a highly reactive alkali metal that is commonly found in nature bonded to other elements in compounds. It is not found in its pure form due to its reactivity.
An example of a compound that contains potassium is potassium chloride (KCl), which is commonly used as a salt substitute.

smaller volume > crowded particles > more collisions > higher pressure
(2) an ionic bond
(3) a nonpolar covalent bond
(4) a polar covalent bond
To solve this we must be knowing each and every concept related to an ionic bond. Therefore, the correct option is option 2 among all the given options.
Ionic bond, also known as electrovalent bond, is a kind of connection generated in a chemical molecule by the electrostatic attraction of oppositely charged ions.
Whenever the valence (outer portion) electrons with one atom are permanently transferred to another, a bond is formed.
The atom that loses electrons has become a positive ion (cation), whereas the atom that obtains electrons is becoming a negatively charged ion (cation) (anion). When one or more valence electrons are transferred from one atom to another, then the bond formed is an ionic bond.
Therefore, the correct option is option 2 among all the given options.

The type of bond that results when one or more valence electrons are transferred from one atom to another is the ionic bond. The answer is number 2. The rest of the choices do not answer the question above.
