How many hydrogen atoms can bind to one carbon atom? How many electrons are in a double bond? What is the maximum number of single covalent bonds a carbon atom can form with other elements? How many electrons are there in an atom of carbon?
How are valence electrons related to ionic bonds? How does a polar covalent bond differ from a nonpolar covalent bond? What is a covalent bond in chemistry? What type of bond is formed in a covalent compound? How can electronegativity cause a covalent bond to be polar?
While the FDA prohibits bottled water manufacturers from implying that their water is "safer" or "purer" than any other kind of water, implications are a difficult thing to quantify. In any event, many bottled-water drinkers believe they are drinking something that is healthier than tap water....
The phosphate of one nucleotide is covalently bound (a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form ...
How to Balance a Redox Reaction: Redox reactions are chemical reactions that involve the transfer of electrons between two substances. Examples of redox reactions can be found everywhere in the world and in every aspect of life. From the combustion of fi
In abond, atoms can either share electrons (covalent) or give them up (ionic). The atom that holds the electrons closer will thus be more negatively charged than the other atom. Electronegativity is a measure of how much a particular element wants electrons. In the Resources section you will...
Electron dot structures, also called Lewis structures, are a graphical representation of the way electrons are distributed throughout a compound. Each element's chemical symbol is surrounded by lines, representing bonds, and dots, representing non-bonded
To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if someone they suspect has been drinking is actually legally drunk? Many officers in the field rely ...
The plan of this work is the following: (i) Starting from quantum mechanics of a system made up of nuclei and electrons, we derive a representation of the system made up of classical nuclei and quantum electrons. Then we show that under a large set of conditions of interest for systems ...
A single 4p orbital can hold how many electrons? An atom in ground state contains 18 electrons. How many of these electrons are in orbitals with, l=0? a. 4 b. 2 c. 8 d. 6 The configuration of S is 1s22s22p63s23p4. How many orbitals are occupied by at least one elect...
