If compounds exist as molecules then why is it impossible to have an atom be compound?
Compounds and molecules are composed of several atoms - by definition. You can have substance that is made of one single element. For instance, many metals exist as pure substances that are not compounds. However, the word compound itself implied that it is composed of more than one thing, not just a single type of atom.

Why do you use the term formula mass instead of molecular mass for ionic compound?
We use the term formula mass for ionic compounds because they do not exist as discrete molecules like covalent compounds. Instead, ionic compounds exist as a three-dimensional array of ions arranged in a crystal lattice. Therefore, the term formula mass better reflects the overall mass of the compound, considering all the atoms and ions present in its formula unit.
Is tabel salt a compound or a molecule?
Compounds are substances (things made out of only one type of chemical) made of molecules - i.e., like an atom is to an element, so a molecule is to a compound. Thus in general terms, a single unit of table salt is a molecule (though more technically it is a formula unit, since it is an ionic compound. Ionic compounds don't usually exist as just one unit, though the concept is useful for calculations, hence the distinction) and a bunch of units of table salt is a compound. everything is made of molecules is also a compound so both
Can something be a compound and molecule?
Yes. Eight elements exist as diatomic molecules. They are hydrogen (H2), oxygen (O2), nitrogen (N2), fluorine (F2), bromine (Br2), chlorine (Cl2), iodine (I2), and astatine (At2). Molecules that are compounds contain two or more elements. Examples include water, H2O, carbon dioxide, CO2, and glucose, C6H12O6.
Is PCl you binary molecular compound?
The compound PCl don't exist; all phosphorous chlorides are binary compounds.
Is The overall charge of an molecular compound must be neutral?
Yes, the overall charge of a molecular compound must be neutral. This is because molecular compounds are formed by the sharing of electrons between atoms, resulting in neutral molecules. While individual atoms within the compound may have positive or negative charges, the total charge must balance out to zero for the compound to be stable and exist as a neutral entity.
Is a molecule also a compound?
Not necessarily. A molecule is the smallest unit of a chemical compound that can exist independently, while a compound is a substance made up of two or more different elements chemically bonded together. All compounds are molecules, but not all molecules are compounds.
Why do you use the term formula mass instead of molecular mass for ionic compound?
We use the term formula mass for ionic compounds because they do not exist as discrete molecules like covalent compounds. Instead, ionic compounds exist as a three-dimensional array of ions arranged in a crystal lattice. Therefore, the term formula mass better reflects the overall mass of the compound, considering all the atoms and ions present in its formula unit.
Why elements and all compound exist as molecules?
Elements can exist as molecules when they combine with other elements to form compounds due to the sharing or transfer of electrons, creating stable structures. These molecules are held together by chemical bonds, which can be covalent, ionic, or metallic, depending on the types of elements involved. The formation of molecules allows the elements to achieve a more stable configuration, following the octet rule and minimizing their energy state.
A single unit of an ionic compound is referred to as a molecule?
Actually, a single unit of an ionic compound is referred to as a formula unit. Unlike molecules, ionic compounds do not exist as discrete molecules but as an arrangement of ions in a crystal lattice.
Is all molecules compound?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
An ionic compound is a compound that consists of molecules made of atoms that are covalently bonded.?
false
Are molecules only found in compounds?
No, molecules can exist both in compounds and as individual elements. In compounds, molecules are formed when atoms chemically bond together. In the case of elements, some exist as diatomic molecules (like oxygen, O2), while others exist as single atoms (like helium, He).
Does the chemical formula of an ionic compound show the atoms in a molecule?
No, the chemical formula of an ionic compound does not show the atoms in a molecule. Instead, it represents the simplest ratio of ions in the compound. Ionic compounds exist as a lattice structure of alternating positive and negative ions, rather than discrete molecules.
Do ionic compounds exist as molecules?
No, ionic compounds do not exist as molecules. Instead, they form a lattice structure where positively and negatively charged ions are attracted to each other through electrostatic forces.
An ionic compound is not represented by a molecular formula because an ionic compound?
An ionic compound is not represented by a molecular formula because it does not exist as discrete molecules. Instead, it exists as a three-dimensional array of positively and negatively charged ions held together by ionic bonds. The formula for an ionic compound represents the simplest ratio of the ions present in the compound.
Can you have an atom of a compound like you can an element or can you only have a molecule of a compound?
Yes, elements and compounds can exist separately.
Why all compounds are molecules but not all molecules are compound?
A few elements normally exist as molecules: hydrogen, nitrogen, oxygen, and the halogen gasses of group 7 on the periodic table. Two atoms of these gasses will combine to form a molecule (such as H2, O2, Cl2), but since they are the same type of atom, they are not compounds.
