Learn the definition of the nucleus of an atom. Learn about the particles found in the nucleus and the structure of an atom. Discover the charge of the nucleus. Related to this Question What charge does a proton have? What is the charge of an electron?
What is a negatively charged atom called? Charge: Charge is determined by the ratio of the subatomic particles protons and electrons. Electrons are negatively charged and protons are positively charged so if one particle is more than the other the entity becomes charged. ...
In 1899, Thomson published a description of his version of the atom, commonly known as the "plum pudding model." An excerpt of this paper is found on theChem Teamsite. Thomson's model of the atom included a large number of electrons suspended in something that produced a positive charge gi...
What is the charge on a proton?Sub-atomic Particles:An atom is composed of three different particles that are known as sub-atomic particles. These are neutrons, protons and electrons. The former two are present inside the nucleus. While, the electron is keep revolving around the nucleus....
A silicone compound is made up of a hydrophobic particle dispersed in silicone oil, which produces a foam control used in a great variety of applications.

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-...
