Which type of bonds or interactions between atoms is the strongest? What is the difference between ionic and molecular bonds? What type of bond shares electrons? Why are covalent bonds directional while ionic bonds are not? Explore our homework questions and answers library ...
This rule states that to become stable, an atom has to have 8 electrons in its valence shell. One of the ways by which an atom can achieve this is by sharing their electrons. When electrons are shared between atoms, a covalent bond is formed....
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 ...
The hydrogen atoms in the H2O water molecule form the same kind of covalent bond as in hydrogen gas but with the oxygen atom. The oxygen atom has six electrons in its outermost electron shell, which has room for eight electrons. To fill its shell, the oxygen atom shares the two electrons...

Semiconductors are of 2 Types: AnN-type semiconductoris one that carries current in the form of negatively-charged electrons. This is very similar to conduction of current in a wire. AP-type semiconductoris one that carries current predominantly as electron deficiencies called holes. A hole has ...
All atoms are made up of a positively charged nucleus surrounded by negatively charged electrons. The outermost electrons — the valence electrons — are able to interact with other atoms, and, depending on how those electrons interact with other the atoms, either an ionic or covalent bond is ...
It is created by the movement of electrons or negatively charged particles, between atoms. Depending on the country’s law, electricity may be generated through various means, such as power plants, renewable sources, or coal. Battery Contrary to popular belief, batteries do not store electricity ...
Each covalent bond in the semiconductor, consists of two valence electrons contributed by two neighbouring atoms. When one of the valence electrons leaves the bond, the bond becomes incomplete. This incomplete bond has a strong tendency to complete itself by attracting an electron. The hole is the...
Before understanding what an n-type semiconductor is, we should focus on basic atomic science. Atoms aim to have eight electrons in their outermost orbit, known as valence electrons. Not all atoms achieve this, but they all strive to reach this stable co
