The number of electrons that an atom in the halogen family usually gains or shares?
Nitrogen does not lose or gain electrons. It is a diatomic molecule (N2) and is a molecular compound which has covalent bonding. In other words, the molecule has a triple bond, in which 6 electrons are shared, three for each atom.
Covalent bonds are formed when electrons are what?
Electrons are shared. they may be shared equally if the elements are nearly equal in electronegativity; a nonpolar covalent bond. Or they may be shared unequally, that is the electrons may spend more time in one atoms orbital than the other atoms orbital(s), if the electronegativity variance is great; a polar covalent bond.
How many electrons would carbon have to gain to form a covalent bond?
Carbon atoms do not gain electrons to form a covalent bond. Carbon atoms form four covalent bonds by sharing its four valence electrons with the valence electrons of other atoms. These can be single bonds, in which one pair of electrons is shared; double bonds, in which two pairs of electrons are shared; or triple bonds, in which three electrons are shared; or a combination of these.
How does metallic bonding work?
Much like a covalent bond, the outer electrons are shared between the two atoms. HOWEVER, instead of simply sharing with the immediate neighbor, the valence electrons are shared through out the entire molecule. This allows metals to conduct electricity and to have other properties of metals, like their luster.
Why do some molecules have a pyramidal shape?
The electrons in the atoms shape the molecule. The 'outermost' electrons in the atoms are the most important because they are shared between atoms in the bonds. Electrons repel each other because they have the same negative electrical charge, so the bonds tend to repel each other too. If you have a central atom bonded to each of three identical other atoms, the three atoms will form an equilateral triangle because each of the three bonds is trying to get as far away as possible from the others (by repulsion). If the central atom has a fourth bond orbital that has electrons in it, even without another atom, those electrons will push the equilateral triangle of bonds away (and a little closer to each other), making the molecule pyramidal. Without the fourth bond orbital's electrons, the molecule should be triangular and flat.
Where would you most likely find shared electrons in a water molecule?
You would you most likely find shared electrons in a water molecule near the oxygen atom.

What is Formal charge of the atom?
Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
Are atoms in a molecule held together by shared electrons?
Yes sometimes, that is how covalent bonds are formed.
An oxygen molecule contains a double bond because the two atoms of oxygen share a total of?
Oxygen has 6 electrons in the outer shell. A full shell needs 8 electrons. Each atom therefore needs to 'borrow' 2 electrons from the other. You could therefore consider that 4 electrons are shared in the molecule (each borrows 2 of the others electrons).
What bond occurs when a pair of electrons is unequally shared between two atoms?
In H2O the electrons are shared by the oxygen atom and two hydrogen atoms. Although there are two hydrogen atoms, the electro-negativity (or ability to attract electrons) of the oxygen is greater than the hydrogens, therefore the electrons are pulled greater towards the oxygen resulting in the oxygen becoming "negatively charged" this results in the molecule becoming what is known as a "dipolar molecule". This is what causes water to be attracted to each other as each molecule has a positive and negative pole. Answered by Mason Rawling-Jones (currently 15).
What is the bond called when a pair of electrons is shared equally between two atoms?
This is a covalent bond. If the electron were taken by one or the other atom, it would be an ionic bond. A covalent bond in which the electron(s) spend(s) more time near one or the other atom is a polar covalent bond.
When a molecule has a positive end and a negative end it is called?
Molecules that have partially positive and negative regions are called polar molecules. Polarity results from an unequal attraction of electrons between the atoms that make up a molecule. The electrons are more drawn towards atoms with a higher electronegativity, thus making these atoms partially negative.
Describe the general location of electrons in a covalent bond?
The general location of electrons in a covalent bond is that electrons are shared in pairs between 2 atoms. If 2 electrons pairs are shared, 4 electrons are shared in all. They lie between the two nuclei of the bonding atoms. The shared electrons are typically near the middle of the bond between the 2 atoms, in a covalent bond. They may be slightly closer to 1 atom or the other, due to small differences in electronegativity.
When an atom forms a bond what are the 3 things that its electrons can do?
The electrons can be shared equally (covalent bond). The electrons can be shared but one atom provides those electrons and the other provides none (dative or coordinate covalent bond). The electrons can be donated by one and accepted by the other atom (ionic bond).
What is a force that holds atoms together in a molecule?
Electrostatic attraction for electron pairs hold atoms together. When atoms bond into a molecule, they share electrons, each contributing one electron to a pair. Since the nuclei of the atoms are positive and the electrons are negative, both nuclei are attracted to the shared pair, and stay near each other.
What is the chemical formula for a molecule that contains two chlorine Cl atom is?
Cl2: Chlorine atom is Cl and you want two. Two atoms are single, covalently bonded to each other by one shared pair of electrons (one from each atom): (drawn as hyphen - or two dots .. between the 2 atoms)Cl-Cl or Cl..Cl
