Valence electrons-electrons that are farthest from an atoms nucleus- are the electrons that form bonds with other atoms.
Non-metal atoms form covalent bonds in which their unpaired valence electrons are shared between the atoms. This sharing has the overall effect of giving both atoms an octet of valence electrons, or two valence electrons in the case of hydrogen.
All bonds (single to triple) share two electrons, the one electron is from the first and the other is from the second of the two bonded atoms.
Ionic bond; ionic bonds occur when an element, mainly a metal, loses its electron ( to become positively charged) to an other element, mainly a nonmetal, ( to become negatively charged), to form an ionic compound. For example :- Na + Cl = NaCl
Bonds are formed between two atoms because that results in a more stable state for the atoms. This is a result of electron configuration where most atoms want to have 8 electrons in their outer-most orbital (there are exceptions to this rule, however).
Atoms create a bond many different ways. Covalent bonds - only happens between nonmetals. The atoms share electrons. Ionic bonds - only happens between a nonmetal and a metal. One atom takes the other atom's electron(s). Hydrogen bonds - only happens between hydrogen and fluorine, nitrogen, or oxygen. Polar Covalent Bonds - this is a type of bond between ionic and covalent bonds. The atoms don't share or take the electron. The electron is shared but one atom has more control of it. Metallic bonds - only between metals. Electrons form a shared cloud, not in a molecule, but shared by all the metal atoms in a given object.
Valence electrons-electrons that are farthest from an atoms nucleus- are the electrons that form bonds with other atoms.
Ionic bonds are formed between metal atoms and non-metal atoms. The metal atoms lose electrons and form positive ions, but the non-metal atoms gain electrons and form negative ions. Since the atoms both now have opposite charges, they are attracted to each other and form an ionic bond.However, covelant bonds are formed between two or more non-metal atoms. The atoms share electrons rather than losing or gaining electrons from each other.
An electron, it plays a part in forming/breaking all proper chemical bonds (there are other types of bonds but they don't really cause chemical reactions and as such are rather boring)
Metallic bonds bond identical atoms together if they are both metal atoms, but not if they are other identical atoms. For example, the bonds holding two chlorine atoms together to make Cl2 are not metallic bonds.
Non-metal atoms form covalent bonds in which their unpaired valence electrons are shared between the atoms. This sharing has the overall effect of giving both atoms an octet of valence electrons, or two valence electrons in the case of hydrogen.
All bonds (single to triple) share two electrons, the one electron is from the first and the other is from the second of the two bonded atoms.
covalent bonds is the sharing of electrons between two atoms. polar covalent bonds occurs when one atom is more electronegative than the other and therefore pulls the electron more closely to its atom (the electron is still being shared)
Atoms interact to form molecules by chemical bonds. These chemical bonds can involve sharing electrons between two non metal atoms or they can involve a metal losing an electron to a nonmetal, creating ions and then an ionic bond.
Atoms form bonds by sharing electrons or gaining or losing electrons to other atoms.For example:Carbon forms bonds by sharing four electrons with other atoms.Sodium forms bonds by losing an electron to another atom - that makes sodium positive and the atom such as chlorine that gains the electron positive - so a bond is formed.Chemically joined means that bonds are formed between atoms.
because polyatomic bonds are like ionic bonds where at least it contains a metal and a non-metal.usually in ionic bonds sometimes it's the same thing.also covalent bonds because think of water (h20) the oxygen atom has 6 electrons in it's second shell.it needs two more so that shell is complete two hydrogen atoms can do this job plus that hydrogen atoms have 1 electron in it's first shell and it want's another because the first shell can hold two electrons. all these not complete atoms are like the polyatomic because usually one is non-metal and the other is a metal.
