Reactivity is the property of an atom in which it is either likely or unlikely to form a bond with another atom to create a molecule. The three types of bonds are ionic, covalent, and metallic.Answer and Explanation: The number of valence electrons, the electrons found in the outer ...
The unit cell is the fundamental building block in a crystal lattice responsible for the formation of the whole crystal. If the unit cell form is known, the lattice constant for the cubic lattice can be calculated. The volume for a unit cell is similar to the volume measurement for the ...

2. Specific gravity method. This method calculates the molecular weight by measuring the specific gravity of a Sodium carbonate solution. In the experiment, the solution is placed in a specific gravity bottle, and the mass and volume of the solution inside the bottle are measured. Then, the mo...

The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons an...
We should not think of the universe in the same way. The universe doesn't have an outer perimeter, and nothing exists outside it, because there isn't an outside. As an analogy, consider the shape of our galaxy, the Milky Way. We can infer that it is a spiral based on maps of th...
These mechanisms might be at an atomic level, where the cloud of electrons surrounding the nucleus of an atom is displaced, resulting in an atom having a slightly positive charge on one side and corresponding negative charge on the other. It can also occur at a molecular level, due to ...
As Sellars puts his own view in the first Carus Lecture, “The Lever of Archimedes” (FMPP I §121 note 13): “A more subtle form of this view is one according to which although what is given is in point of fact the sensing of a cool smooth cubical volume of pink, we take this ...
define valency the combining capacity of an atom is known as its valency. the number of bonds that an atom can form as part of a compound is expressed by the valency of the element. we all know how electrons in an atom are arranged in shells/orbitals. valence electrons are those ...
