Yes, atoms with electronegativity differences greater than 1.7 typically form ionic bonds. This is because such a large difference in electronegativity causes one atom to attract the shared electrons much more strongly than the other, leading to the transfer of electrons and the formation of ions.
True. Atoms with electronegativity differences higher than 1.7 generally form ionic bonds due to the large difference in electron attraction between the atoms. This leads to the transfer of electrons from one atom to another, resulting in the formation of ions that are held together by electrostatic forces.
TRUE
No, atoms with electronegativity differences below 0.4 generally form nonpolar covalent bonds. Polar covalent bonds are formed when there is an electronegativity difference between 0.4 and 1.7.
TRUE
Atoms with electronegativity differences below 0.4 generally form nonpolar covalent bonds because the shared electrons are equally attracted by both atoms, resulting in a balanced sharing of electrons. This leads to a stable covalent bond where the electrons are shared between the atoms rather than being transferred.

Atoms with low electronegativity tend to lose electrons more easily, making them more likely to form positive ions. They also have a weaker ability to attract electrons in a chemical bond compared to atoms with higher electronegativity. This can result in them forming bonds with atoms that have higher electronegativity.
The size of an atom inversely influences its electronegativity; as the atomic radius increases, electronegativity typically decreases. This is because larger atoms have their valence electrons farther from the nucleus, resulting in a weaker attraction between the nucleus and bonding electrons. Consequently, smaller atoms, with their valence electrons closer to the positively charged nucleus, exhibit a stronger attraction for electrons, leading to higher electronegativity values. Thus, electronegativity is generally higher in smaller atoms and lower in larger ones.

In a polar covalent bond, the electrons are shared between atoms unevenly due to differences in electronegativity. This results in a slight negative charge on the atom with the higher electronegativity and a slight positive charge on the other atom. The electrons are attracted more to the atom with higher electronegativity, creating a partial separation of charges within the bond.
The shape of the molecule and The electronegativity differences of atoms in the molecule
The electronegativity of the atoms in estrone vary. For example, oxygen is more electronegative than carbon, so the oxygen atoms in estrone will have higher electronegativity values compared to the carbon atoms. It follows the trend where electronegativity increases across a period from left to right on the periodic table.
