What else can I help you with?
Does the more electronegative atom has a slight positive charge in a polar covalent bond?
No, the more electronegative atom in a polar covalent bond has a partial negative charge, while the less electronegative atom has a partial positive charge. This creates a dipole moment in the molecule.
How is the of the second element in a covalent molecule changed?
The ending of the second element is changed to -ide
Is h2co polar or non-polar covalent?
H2CO (formaldehyde) is a polar covalent molecule. The oxygen atom is more electronegative than carbon and hydrogen, resulting in an uneven distribution of electrons and a net dipole moment in the molecule.
How can a covalent bond break?
covalent bonds can be broken if energy is added to a molecule. this formation of covalent bond is accompanied by energy given off.
Why is ammonia polar covalent?
Ammonia is not a polar covalent molecule; it is a polar molecule. The nitrogen in ammonia is more electronegative than the hydrogen atoms, which leads to an uneven distribution of electrons in the molecule, creating a partial negative charge on the nitrogen and partial positive charges on the hydrogen atoms.
Is nh 3 polar covalent or nonpolar covalent?
NH3 is a polar covalent molecule because nitrogen is more electronegative than hydrogen, causing unequally shared electrons and creating a partial positive and partial negative charge in the molecule.
What type of bond is formed between Cl and Br?
A covalent bond is formed between chlorine (Cl) and bromine (Br) when they share electrons to complete their outer electron shells. This sharing of electrons results in the formation of a molecule, such as Cl2 or Br2.
Is HF a covalent molecule?
No, HF is not considered a covalent molecule. It is an ionic compound because there is a significant difference in electronegativity between the hydrogen and fluorine atoms, resulting in the formation of an ionic bond.
What is the name of the structure formed when atoms are joined by covalent bond?
The structure formed when atoms are joined by a covalent bond is called a molecule. In a covalent bond, atoms share electrons to achieve a stable electron configuration, leading to the formation of a molecule.
What is the type of bond that attracts an oxygen and hydrogen molecule?
A hydrogen bond is the type of bond that attracts an oxygen and hydrogen molecule. In a hydrogen bond, the hydrogen atom from one molecule is attracted to the electronegative oxygen atom of another molecule.
What type of chemical bond forms when atoms with high electronegativity react with atoms with low electronegativity?
If the elecrtronegativity difference is greater that 1.7 it is an ionic bond. If it is lower that 1.7 but greater than 0 it is a polar covalent bond. If it is equal to 0 it is a pure covalent bond.
Is a molecule held together by covalent bonds or ionic bonds?
A molecule is typically held together by covalent bonds. Covalent bonds involve the sharing of electrons between atoms, leading to the formation of stable molecules. Ionic bonds involve the transfer of electrons from one atom to another, resulting in the formation of ions that are held together by electrostatic forces.
