Each element on the periodic table is represented by a one or two letter symbol. When the symbol for an element is only one letter the letter is capitalized. When the symbol for an element is two letters the first letter is capitalized and the second letter is lowercase....
Oxygen is the chemical element in the periodic table with the symbol O and atomic number 8. It has 8 protons. It can exist in stable isotopes with 8,9 or 10 number of neutrons. This element belongs to the group of chalcogens and it is a reactive nonmetal which acts as an oxidizing a...
Elemental carbon was known in the forms of charcoal, graphite, and diamond. The Sumerians and Egyptians used charcoal by 3750 BC. Diamonds were known at least as early as 2500 BC. Tin Tinwas smelted with copper to make bronze around 3500 BC in Asia Minor. Archaeologists discovered a cassit...
For instance, burning sodium emits a bright yellow color, whereas copper produces a green flame, and potassium emits a violet hue. In this way, flames serve as a natural spectroscope, offering clues about the elemental composition of the material being burned, helping us parse the relationship ...
is brought up from the Greek word ‘selene’. The meaning of this word is the moon. Selenium is rarely found as pure ore or in pure elemental form. It is generally found in metal sulfide ores. For commercial use, it is mostly produced as a by-product of the refining metal sulfide ...
Platinum is an element with the symbol Pt and number 78. It's a precious, silverish-white transition metal. Platinum consists of six present isotopes. It's one among the rarer elements in the crust, with a mean abundance of roughly 5 μg/kg.

What is a balanced equation for the reaction of aluminum selenide with water? Balanced Equation: A chemical reaction is said to be balanced if the number of atoms of each element and the total charge is same for both the reactants and the products. Thus, we can say that ...
An alloy of aluminum that contains copper, manganese, magnesium, iron, and silicon and is resistant to corrosion by acids and seawater. Aluminium A light, silvery metal extracted from bauxite, and a chemical element (symbol Al) with an atomic number of 13. Duralumin (metallurgy) An alloy of...
Thirdly, there is the element assimple substance. Arealphysical 5.00g piece of copper metal has numerous, measurable, intrinsic properties such as: density, conductivity, colour, purity, etc. Crucially, these properties are NOT conserved when the copper undergoes chemical reactions, such as dissolving...
