All the elemental gases except for the Noble Gases come in what kind of special molecules?
All the elemental gases except for the noble gases come in molecules that are unstable. The noble gases are all stable, they have the maximum number of valence electrons that their outer shell can hold.
What atoms generally form covalent bonds?
Covalent bonds form between non-metal molecules. Covalent bonds come in 2 kinds: polar and nonpolar. If the two atoms bonding have an electronegativity difference of less than .5, then the bond is usually considered nonpolar covalent. If the difference is greater than .5 but less than 2 the bond is usually considered polar covalent.
What bonds are in DNA and where are they found?
There are two types of bonds in DNA: phosphodiester bonds and hydrogen bonds. The phosphodiester bonds are the strong covalent bonds that create the phosphate-deoxyribose backbone. The hydrogen bonds links the "rungs" of the ladder, between nitrogen bases.
Name and describe the 3 types of chemical bonds?
Ionic BondsIonic bonds form when two atoms have a large difference in electronegativity. A Ionic bonds often occur between metals and salts; chloride is often the bonding salt. Ionic bonds can typically be broken through hydrogenation, or the addition of water to a compound. Covalent BondsCovalent bonds often form between similar atoms, nonmetal to nonmetal or metal to metal. Covalent bonding signals a complete sharing of electrons. Covalent bonds are usually strong because of this direct bonding. Polar Covalent BondsPolar covalent bonds fall between ionic and covalent bonds. One atom becomes slightly negative and the other atom becomes slightly positive. Polar covalent bonds often indicate polar molecules, which are likely to bond with other polar molecules but are unlikely to bond with non-polar molecules.
How come helium has only 2 electrons and is a member of the noble gas?
a noble gas has a full outer shell; in the case of helium the 1s shell is full making it stable and dose not want anymore electrons making it have a low reativity just like the rest of the noble gases
Why do coordinate covalent bonds differ from regular covalent bonds?
They only differ from regular covalent bonds because both oth electrons come from one atom. In other respects a coordinate covalent bons is simply a covalent bond as both electrons are shared between two atoms.
Are molecular and covalent bonds the same?
Molecular and covalent bonds aren't really the same. It is chemical bonds that hold molecules together. These chemical bonds might be called molecular bonds, and they come in two basic flavors: ionic bonds and covalent bonds. A molecular bond might be covalent, but it might be ionic, and that's the difference.
Valence electrons can come together to form what kind of covalent bonds between atoms?
Valence electrons can come together to form single, double, or triple covalent bonds between atoms.
Is covalent bonding soluble in water?
Covalent bonds themselves are not soluble in water because they are intramolecular bonds within compounds. However, some covalent compounds can be soluble in water depending on their polarity and ability to form hydrogen bonds with water molecules.
All the elemental gases except for the Noble Gases come in what kind of special molecules?
All the elemental gases except for the noble gases come in molecules that are unstable. The noble gases are all stable, they have the maximum number of valence electrons that their outer shell can hold.
What is a compound made from a group of covalent bonds?
A compound made from a group of covalent bonds is a molecule. A molecule is formed when atoms come together and share electrons through covalent bonds to achieve stability. These covalent bonds hold the atoms together in a specific arrangement to form a distinct chemical entity with its own unique properties.
Which group of elements is very stable and nonreactive?
Noble gases are the group of elements that are very stable and nonreactive due to their full outer electron shells, which gives them little tendency to gain, lose, or share electrons to form chemical bonds.
What input is necessary for the breaking of covalent bonds, which requires the input of energy?
The breaking of covalent bonds requires the input of energy. This energy can come from various sources such as heat, light, or electricity.
What atoms generally form covalent bonds?
Covalent bonds form between non-metal molecules. Covalent bonds come in 2 kinds: polar and nonpolar. If the two atoms bonding have an electronegativity difference of less than .5, then the bond is usually considered nonpolar covalent. If the difference is greater than .5 but less than 2 the bond is usually considered polar covalent.
How come noble gases do not compounds readily?
Their outer energy levels are completely filled.
What are the covalent bonds and ionic bonds?
Ionic Bonds- When a metal and a nonmetal come together and loses or gains an electron. Covalent Bonds- Two nonmetals that share one or more electrons. Both bonds bonds together to form a stable, complete or filled outer shell of 8 valance electrons.
What intermolecular force holds water molecules together?
Chemical bonds come in two varieties. They can be either covalent or ionic. The bonds where they share electrons is called covalent bond and is stronger than ionic bonds where one molecule gives up its electrons to the other.
