A type of atom can be of any type. Elements are pure chemicals that cannot be converted into more basic compounds by conventional chemical processes.

A chemical element is a substance that cannot be disassembled chemically or physically into simpler substances. Chemical elements are the basic building blocks of matter because they are pure substances made up of atoms with the same atomic number (number of protons) in their nuclei. A chemical element is essentially a pure substance that cannot be disintegrated, degraded, or changed into other compounds through physical or chemical methods.

A chlorine (CI) atom has 7 valence electrons. Which of the following would be the most likely way for a chlorine atom to become
pogonyaev

Answer:

Option C. Gain 1 electron

Explanation:

Valence electron(s) are the electron(s) located on the outermost shell of an atom. Valency is simply defined as the combining power of an atom.

Chlorine (Cl) atom has 7 valence electron. This implies that Cl needs just one electron to complete it's octet configuration. It will be difficult for Cl to lose any of it's valence electron(s). Cl can either gain or share 1 electron to become stable.

Thus, considering the options given in the question above, option C gives the correct answer to the question.

Give an example of a substance that is MORE dense in its solid state when compared to its liquid state.
Natalka [10]

Answer: Wax

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Usually solids are more denser than liquid, as molecules in solid are more strongly packed and thus have more mass per unit volume.

Liquids on the other hand contain molecules which are less tightly bound and thus thus contain less mass per unit volume as compared to solid.

Example: Solid wax is more denser than liquid wax.
