The Philippine Charity Sweepstakes Office (PCSO, Filipino: Tanggapan sa Charity Sweepstakes ng Pilipinas[2]) is a government-owned and controlled corporation of the Philippines under direct supervision of the Office of the President of the Philippines. It is mandated to do fund raising and provide funds for health programs, medical assistance ...
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}} (An overview is here). See also [ edit ]
The increase in the oxidation state of an atom, through a chemical reaction, is known as oxidation; a decrease in oxidation state is known as a reduction. Such reactions involve the formal transfer of electrons: a net gain in electrons being a reduction, and a net loss of electrons being oxidation. For pure elements, the oxidation state is zero.
the transition metal elements from group 4 to group 9 (titanium group to cobalt group) should be able to display the negative oxidation states which have the same parity as their group number (e.g, ruthenium is in group 8 an even number-so are its negative oxidation states -2 and -4). most of them also show the -1 oxidation state regardless of ...
Bromine compounds are compounds containing the element bromine (Br). These compounds usually form the -1, +1, +3 and +5 oxidation states. Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
