Electronegativity:An atom of a chemical element participates in a covalent bond when it shares one or more of its available valence electrons. The concept of electronegativity refers to this type of chemical bond. As the participating atom becomes more electronegative, the...
What type of chemical bond connects atoms that equally share electrons such as the bonds between a hydrogen atom and a carbon atom in methane? In terms of hydrogen bonding, which is more stable, an A-T base pair or a G-C base pair? What is ...
How is a covalent bond formed? Covalent bonds, which hold the atoms within an individual molecule together, are formedby the sharing of electrons in the outer atomic orbitals. The distribution of shared as well as unshared electrons in outer orbitals is a major determinant of the three-dimensio...
aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so H2O can form four hydrogen bonds. [translate] ...

A bond in which electrons are shared between atoms is: a) reciprocal b) di-electron c) covalent d) ionic The element carbon has ___ electrons in its outer shell. a. 0 b. 1 c. 2 d. 3 e. 4 f. 12 What are the cations and anions ions in...
A: We now organize the table based on quantum theory—on the positions the electrons in the outer shell of an atom have. That explains their chemical properties because the electrons determine how they bind with other elements. Mendeleev didn't know any of that. The electron was discovered in...
