The strength of an electromagnet is proportional to its current, so an increase in current correlates to an increase in the strength of the magnetic field created. There are several ways to control the current, and in tu... More » Science Chemistry Atoms & Molecules

The properties of the oxygen family include the fact that, as atomic numbers increase, the elements in the family increase in metal similarity and decrease in electronegativity. All elements in the family exist in a natu... More »

Leptons and quarks constitute the smallest particles of matter, based on contemporary evidence in the field of particle physics. Traditionally, the atom was considered as the indivisible form of matter. More »

The Eyring Equation, also called the Eyring-Polanyi Equation, is used to calculate the rate of a chemical reaction at different temperatures in the field of chemical kinetics. It is written as k = (k_b[t])/h) * e^(-delta... More »

Pure aluminum has a yield strength of between 7 and 11 megapascals (MPa). Aluminum is often alloyed with other metals to increase its yield strength. Some aluminum alloys are rated as being able to withstand between 200 ... More »

Mild steel has a yield strength of 60,200 pounds per square inch (psi), a tensile strength of 78,300 psi, a modulus of elasticity of 29,000 psi, and a Poisson's ratio of 0.29. More »

The strength of attraction for a metal ion is dependent on several factors. The ionic charge can be determined by how many valence electrons it donated and the element's position on the periodic table. It is more common ... More »
