The key difference between atomic weight and mass number is that atomic weight is the average mass calculated considering all the isotopes whereas mass number is the mass of a specific isotope. We can characterize atoms by their atomic numbers and mass numbers. In the periodic table, atoms are arranged according to their atomic number. […]
Difference Between Molecules and Compounds
The key difference between molecules and compounds is that molecules form by the combination of the same or different elements while compounds form by the combination of different types of chemical elements. Atoms are the tiny units that form all chemical substances. Moreover, atoms can join with other atoms in various ways and form thousands […]
Difference Between Calories and Kilojoules
The key difference between calories and kilojoules is that one calorie equal 4.184 kilojoules. Calories and kilojoules are units that we can use to measure the energy. Usually, we use these two words in measuring food energy. It is necessary to indicate the amount of energy contained in each food item on their packaging. Some […]
Difference Between Atomic Weight and Atomic Mass
The key difference between atomic weight and atomic mass is that atomic weight is the average weight of an element, with respect to all its isotopes and their relative abundances but, atomic mass is the mass of a single atom. Most people use the terms atomic mass and atomic weight interchangeably. However, they bear different […]
Difference Between Oxygen and Air
The key difference between oxygen and air is that oxygen is an individual gaseous component that exists as a part of air whereas air is a mixture of several gases. Air or atmosphere is a main component of the Earth, other than water (hydrosphere) and soil (lithosphere). Four and a half billion years ago, when […]
Difference Between Renewable and Nonrenewable Resources
The key difference between renewable and nonrenewable resources is that the renewable resources are those that can replenish themselves and are infinite in supplies whereas the nonrenewable resources are resources that are limited in supplies. Here, the term resources refer to energy forms or any other useful source that we use in different applications. We […]
Difference Between Boiling Point and Melting Point
The key difference between boiling point and melting point is that boiling point is the temperature at which a liquid state changes to its gaseous state whereas melting point is the temperature at which a solid state changes into a liquid state. There are three states of matter: solid state, liquid state and gaseous state. […]
Difference Between Fluorine and Fluoride
The key difference between fluorine and fluoride is that fluorine is neutral whereas fluoride is negatively charged. The elements in the periodic table except the noble gases are not stable. Therefore, elements try to react with other elements to gain the noble gas electron configuration and achieve stability. Fluorine is an element that also has […]
Difference Between Atom and Ion
The key difference between atom and ion is their charge; atoms are neutral while ions are charged positively or negatively. Atom is the smallest neutral unit which can form bonds while ion is any charged molecule. Ion may be composed of several atoms or a single atom. Atoms are unique and do not differentiate into various […]
Difference Between Steam and Vapor
The key difference between steam and vapor is that steam is the gaseous state of water whereas vapor is the gaseous state of any substance. We use the term “steam” as a common name to name water vapor specifically. The gaseous state of any other matter is “vapor”. Therefore, the use of the term is […]
