First of all
Fe is Iron, and a sample of Iron would just be pure Iron thus there wouldn't be any "bonds"
Second of all
Fe is a metal thus cannot have a covalent bond. If it bonds, it is usually an ionic bond with non-metal i.e. Oxygen to make rust
FeCO3 contains both ionic and covalent bonds. The Fe-C bond is mainly covalent, as both atoms share electrons, while the Fe-O bond is ionic, as Fe donates electrons to O to form a bond.
No such molecule as 'FeOH'. It is either Fe(OH)2 or Fe(OH)3 The bond between iron(Fe) and the hydroxide ion (OH) is ionic. However the bond between the O & H in the hydroxide moiety is covalent. Fe(OH)2 = Fe^(2+) + (O-H)^(-) + (O-H)^(-) or shortenede down Fe^(2+) + 2(O-H)^(-)
It is ionic
FeNi is an intermetallic compound with a metallic bond. In this case, the bond between iron (Fe) and nickel (Ni) is considered metallic rather than ionic or covalent.
No they have a covalent bond due to because of their electronegativities.
The type of bond in which two atoms share electrons is called a covalent bond.
covalent bond,coordinate bond and singlet bond
Assuming you are referring to only two hydrogen atoms, such as in a sample of hydrogen gas, there is a covalent bond between the hydrogen atoms, as well as a small amount of dispersion forces.
covalent
Hydrogen chloride has a covalent bond.
FeO is an ionic bond. Iron (Fe) is a metal and oxygen (O) is a non-metal, so they tend to form an ionic bond where Fe loses electrons to form Fe2+ cation and O gains electrons to form O2- anion.
A covalent bond which is either double or triple covalent bond.
