These bonds are covalent.
The electrons in the valence shell are those most concerned with bonding and how that occurs. The "non-bonding" electrons are the ones in the inner shells, or the non-valence shells of an atom. Non-bonding electrons are also found in the valence shell. They are referred to as lone pairs. For example, in ammonia (NH3), nitrogen has one lone pair. In most circumstances, lone pair electrons do not form bonds (they do in a special type of covalent bond).
There is no solid evidence that suggests that ingesting normal quantities of aspartame leads to health problems. However, aspartame is not a normal part of the human diet. Furthermore, the FDA's ultimate approval of aspartame as a food additive is highly suspicious. For some insight into how aspartame passed the FDA approval process, go to the link below:http://www.stevia.net/aspartame.htm
Because the atoms having covalent bonds "share" the involved electrons equally. This is one of the effects of Quantum Mechanics, the shape of the orbital probability cloud containing the electrons in these bonds changes shape to encompass both atoms valence bands.
If this clotting occurs in the larger arteries, it results in major tissue damage.
The fall equinox occurs in September in the Northern Hemisphere.
The molecules haves secondary types of bondings as 1- Dipole-Dipole interaction, 2- Vander waal's bonding and 3- Hydrogen bonding, depending upon nature of molecules.
Synthesis
the hydrogen bonding is possible in oxygen, nitrogen,and fluorine
No, hydrogen bondng only occurs in molecules where hydrogen (H) bonds with nitrogen (N), Oxygen (O) or fluorine (F)
covalent bonding
You don't. A triple bond occurs between two atoms that each have either three or four bonding sites. Nitrogen molecules and acetylene molecules have triple bonds. Hydrogen atoms have one bonding site.
Covalent Bonding
Metallic bonding
The bonding in transition metals involves both a "covalent" contribution and a metallic "cloud of electrons bond. Alkali metals just have the cloud of electrons to hold them together- hence softer and lower melting.

Covalent bonding
Ionic bonding occurs between a metal and a nonmetal whereas covalent bonding occurs between two nonmetals.
