What is the mass number of argon? What is the mass number of carbon-12? How many protons, neutrons, and electrons does silicon have? What is the formula for mass number? What is the classification of silicon? What is the mass number of molybdenum?
It is known that molecules or formula units are formed by the sharing of electrons (molecular bonds) or ionic charge attraction, respectively. Many compounds of chlorine are binary, where only chlorine as chloride bonds to one ion or atom....
Makeup of Table Salt Though table salt may be what comes to mind when you think 'sodium,' it is actually a compound, meaning it has more than one component. Table salt is sodium chloride, and is made up partly of sodium atoms and partly of chlorine atoms. ...
Each of its molecules has iron in the center, which allows it to move four bits of oxygen. When the mineral is low, the carrying capacity of the hemoglobin is reduced. Did you know? Red blood cells and hemoglobin are made in the bone marrow and are found inside long bones like the...
(Chemistry) Any of two or more substances that have the same molecular formula but differ in the way their atoms are connected to each other, in the spatial orientation of their atoms, or, in the case of large molecules such as DNA, in their molecular topology. Isotopes Plural of isotope...
Even chemically pure, neutral water contains hydrogen ions due to the autodissociation of water [1]. In this process, water molecules are broken up into simpler constituents (i.e. ions). [1] H2O ⇔ H++ OH- In this reaction, H2O is deprotonated (i.e. loses a proton). This results...
What is the hybridization of the central atom in NI3? Nitrogen triiodide: Nitrogen triiodide is a compound of nitrogen and iodine as it is made up of one nitrogen and three iodides. It is an unstable compound as there is steric hindrance due to the small size of nitrogen. The shape of ...
Thyroid hormones are made from molecules oftyrosine, a type of amino acid, and iodine. Thyroxine, or T4, is made of two tyrosines and four iodine atoms while triiodothyronine, or T3, also consists of two tyrosines but with only three iodine atoms joined on. Removal of an iodine atom conver...
empty space between the gas molecules. Gases can be ''invisible'', such as the air we breathe, or visible, such as iodine or bromine gas. We are surrounded by gases, and two are very important to our lives in the form of oxygen and carbon dioxide, with oxygen being ever so critical...
What is a Lewis dot symbol? To what elements does the symbol mainly apply? 1. Identify the correct Lewis electron-dot symbol for the ion formed from each of the following atoms: a. Mg b. N 2. Predict the formula of their compound. ...
