Chemical compound

iron, copper or calcium or non-metals such as carbon, oxygen or nitrogen. Chemistry is concerned with the way atoms link together to form molecules, which are the natural chemical units of matter. Molecules represent the smallest particle of a chemical compound which retains the characteristics and chemical properties of the compound. With the rare exception of certain single atom molecules, almost all molecules consist of two or more atoms linked together. An atom of the violently active metal…

one elements? Group one elements are alkali metals. The physical properties of group one elements are that they are shiny and the alkali metals are very soft. Lithium is the hardest alkali metal and they become softer as you go down the group. The chemical properties of group one is that they’re very reactive when mixed with water or when in contact with the air. Each element in group one has one electron in their outermost shell. Also, group one elements get more reactive as you go down; this…

all forms of life include: as a nutritional supplement, in the preparation of pharmaceuticals and as a nutritive feed for poultry and livestock. Selenium Physical and Atomic Properties A number of selenium exists with different physical and chemical properties. For that reason, selenium exists in a number of allotropic forms. There are two main allotropes of selenium, one is an amorphous red powder and the other is a bluish with a metallic appearance. Further number of Selenium allotropes…

nuclear reactors, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself. The biological role is essential to all living things, and humans have known this since prehistoric times. Our bodies contain about 100 grams, but we are constantly losing sodium in different ways so we need to replace it.…

our basis on whether the element gained or lost electrons in chemical reactions. We can say that an element is in its Oxidation State when the element already has a specific ON. Unlike with our previous examples, not all equations would already reveal the ON of each element. In actuality, equations would only be presented as is and we will be the ones assigning the ON. In order to properly delegate the ON of the elements or compounds, the following rules should be followed and observed. It is…

Molecules are a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central…

otherwise acquire, transfer directly or indirectly, receive, stockpile, retain, own possess or use or threaten to use any chemical weapon’. Chemical weapon is defined as ‘a toxic chemical and its precursors …any chemical which through chemical action on life processes can cause death, temporary incapacitation or permanent harm to humans or animals…includes all such chemicals, regardless of their origin or of their method of production and regardless of whether they are produced in facilities,…

Additionally, the shapes of NH3 and PH3 are quite similar, as they both use Trigonal Pyramidal (Four Subtituents) Geometry. NH3 would ultimately have a stronger attraction, due to nitrogen's higher level of electronegativity.This particular chemical compound is identified as Copper (II)…

Ans Decision tree analysis will involve step determination of the chemical and physical characteristics of this chemical. By knowing them, it will be very easy to determine the best control method to be employed. Firstly, the compound is corrosive and it therefore suggests that it is highly reactive and use of water and any other chemicals that can lead to an undesired chemical reaction will be ruled out. Also, the spilled chemical is producing fumes, mostly it suggests that it is either a…

a unit of measurement used for chemicals. The unit “mole” can also be abbreviated as “mol”. “Moles are used so that chemists, scientists or engineers know how much of different kinds of chemicals to use to have reactions that work out right. When chemists want to have a chemical reaction come out they need to know how many molecules of each kind of chemical they have, so they measure the chemicals in moles. A mole is the atomic weight of a molecule of the chemical in grams” ("Propulsion." What…
