Herein, we describe a new silicon tetraamidinium compound and use it to prepare crystalline hydrogen bonded frameworks with carboxylate anions in water. The silicon-containing frameworks are compared with those prepared from the analogous carbon tetraamidinium: when biphenyldicarboxylate or tetrakis(4-...

What is catenation? Properties of Carbon Carbon is element number 14 on the periodic table. It has a molecular weight of 12 g/mol. Each carbon atom has four electrons available to form covalent bonds. Diamond and graphite are two of the most common natural forms of carbon that exist. These...
What is the Intel® Atom® Processor? The Intel® Atom® Processor is a family of low-power CPUs designed for use in mobile devices such as smartphones, tablets, and embedded systems. It is optimized for energy efficiency and long battery life. ...
Electronegativity - The electronegativity of an element is the ability of an atom of that element to push electron density within a covalent bond towards itself. Allotropes - Allotropes of an element are different forms of an element that occur in the same physical state. Atoms of the element...
Methylation is a simple biochemical process. It is the transfer of four atoms – one carbon atom and three hydrogen atoms (CH3) – from one substance to another. The addition of methyl groups can affect how some molecules act in the body. What is methylation in the body? When optimal meth...
The number of protons in an atom is called the atomic number and it tells you what type of atom you have. An atomic number of 1 means the atom is hydrogen, atomic number 2 means helium, 3 means lithium, 4 is beryllium, and so on. The total number of protons and neutrons added ...
Less commonly, carbon forms ionic bonds with other atoms. This occurs when there is a large electronegativity difference between carbon and the other atom. Carbon Forms Covalent Bonds The most common type of bond formed by carbon is a covalent bond. In most cases, carbon shares electrons with ...
