This all has to do with the difference in electronegativity between the two atoms. The electronegativity is a measure of how strongly an atom attracts electrons. If they both attract electrons with about the same affinity (not a big difference in electronegativity), then you have a covalent bond, and they SHARE the electron(s) equally or almost equally.
Phosphorus is a chemical element, not a compound.
H2O is a covalent compound. As hydrogen has only one electron in its outer most shell and oxygen has six electrons in its last shell. Oxygen needs two, while hydrogen requires only one electron to complete its last octave. So oxygen form two covalent bond with two hydrogen atoms. So, water is a covalent compound, but as oxygen is second most electronegative element in the periodic table so due to its high electronegativity the bond no more remains pure covalent, but converted to polar covalent. Hence, water molecule is a polar covalent compound.
It forms the fluoride by forming an ionic or covalent bond with the element.Example:-HF(hydrogen fluoride) which if an ionic compound.OF2(Oxygen difluoride) which is a covalent compound
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
Oxygen is the most commonly found element as part of a compound with another element. This is because oxygen has a high electronegativity and readily forms chemical bonds with other elements. Additionally, oxygen is abundant in the Earth's atmosphere, making it readily available for chemical reactions.
a coordinate covalent bond is formed by shearing of pair of electron in which one element work as DONNER and give to another element who works as ACCEPTOR and take one pair of electron to form coordinate covalent bond example NH4Cl a covalen bond is that in which mutual shearing of electron is done
No, F2 is covalent but it is an element, not a compound.
P2O5 is not an element. It is a compound with polar covalent bonds.
Iron is a chemical element, not a compound.
Iron is not a compound, it is a metallic element.
No, carbon is an element.
Electrons are transferred from one element to another. when electrons are shared this is a covalent bond.
F2 is fluorine, which is an element, not a compound.
Phosphorus is a chemical element, not a compound.
Xenon is a noble gas in with the electrone of outermost orbit are balanced than the xenon cannot make ionic bond with another element such as Oxygen because if it make an ionic bond than the electron of the outer most orbit are unstable therefore it make an covalent bond with oxygen to fill the outer most unbalance electron of oxygen by sharing electron to form (xenon oxide) (xenon dioxide) and also with floride to form (xenon difloride) etc.
SiF4 is a polar covalent compound
Alcohols have covalent bonds.
