A pure element is a substance consisting of only one isotope of a single element. Isotopes are atoms that differ from the atomic weight usually associated with a particular element due to having a different number of neutrons in their nuclei.
An element is a specific substance, such as gold, iron or carbon, that cannot be broken down into another substance by chemical means. Elements consist of atoms that all have the same number of protons. Atomic nuclei are made up of protons and neutrons almost always in equal numbers. If an atom has a different number of neutrons, the physical properties of the atom are altered, but these isotopes are still able to chemically bond with other atoms just like fellow atoms of the same element with the usual number of neutrons. A pure element contains atoms of only one isotope, so every part of the substance has the same physical properties.Learn More
Neon was discovered by freezing the chemical element argon using liquefied air. The gas that vaporized from the mixture was subjected to a high voltage to obtain its spectral lines. The crimson light that the gas emitted had never been recorded before, hence, the new element was given the name neon from the Greek neos, which means new.Full Answer >
Titanium is significantly stronger than platinum. In fact, titanium is the hardest natural metal. Titanium products do not dent, bend or scratch as easily as platinum items.Full Answer >
The visible color in the hydrogen spectrum with the lowest frequency is red. Red has the longest wavelength, and therefore the lowest frequency, of any visible color. Hydrogen emits red at a wavelength of 656.2 nanometers.Full Answer >
Carbon's atomic number is 6, and its atomic mass is 12.0107 atomic mass units. The atomic number defines the number of protons located in the atom's nucleus, so carbon has six protons. Each element has its own atomic number.Full Answer >
