What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...
Classify the following elements as metals, metalloids, or nonmetals: a. Phosphorus b. Chlorine c. Germanium d. Cobalt e. Sulfur List the symbols and names for two alkali metals, two noble gases, and two halogens. Classify Element 79 as metal, nonmetal, or metalloid. Is it a noble gas ...

In its pure form, mercury is an element -- symbol Hg on the periodic table, metallic, atomic number 80. It's a silvery substance that's liquid at room temperature, and it's naturally occurring. Some estimates put the amount of mercury emissions from natural activities, like volcanic eruptio...
Atomic oxygen refers to individual oxygen atoms, highly reactive and rare on Earth's surface, while molecular oxygen (O2) is a stable diatomic molecule, essential for respiration and common in Earth's atmosphere.
Iron () is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. Metal A solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electri...
Thus while Mendeleev was able to predict the existence and the chemistry of the missing elements eka-boron, eka-aluminium, and eka-silicon (scandium, gallium, and germanium) with considerable certainty, he was much more tentative when it came to other elements. In his Faraday Lecture of 1889 ...
The quantum mechanical approach is currently used to explain atomic structure. The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about someand some...
