Notable symptoms of a pulled muscle in the chest are within 24 hours after the injury. The most evident is in the chest, which feels like a sharp burning pain during movement or rotation.
Question and answer. Which of the following are likely to form an ionic bond? silicon and oxygen oxygen and oxygen carbon and hydrogen magnesium and oxygen. Carbon and hydrogen are likely to form an ionic bond.
You can predict an ionic bond will form when two atoms have different electronegativity values and detect an ionic compound by its properties, including a tendency to dissociate into ions in water. Covalent Bonds. In a covalent bond, the atoms are bound by shared electrons. In a true covalent bond, the electronegativity values are the same (e.g., H 2, O 3), although in practice the electronegativity values just need to be close. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar. Usually, an electron is more attracted to one atom than to another, forming a polar covalent bond. For example, the atoms in water, H2O, are held together by polar covalent bonds.
