Which of the following describes the electron sharing between hydrogen and fluorine? Hydrogen and fluorine share one electron with each other.
What changes involve forming or breaking chemical bonds?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What kind of change happens when chemical bonds break and new bonds form?
Answer and Explanation: When chemical bonds break and new bonds form, new substances are generated. This is known as a chemical reaction.
What is the energy released when chemical bonds are broken and reformed?
Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.
What describes the electron sharing between hydrogen and fluorine?
Hydrogen fluoride is formed through covalent bonding (electron sharing) between a hydrogen atom and a fluorine atom. Hydrogen contains one electron, and fluorine requires one electron to become stable, so the bond forms readily when the two elements interact.
The hydrogen and fluorine atoms are bound together by a pair of electrons, one electron contributed by the hydrogen atom and one by the fluorine atom. Although the electrons are shared between the hydrogen and the fluorine atoms, in…
Which of the following describes the electron sharing between two oxygen atoms?
When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons. In this case, two electrons from each atom are shared. This is called a double bond.
What is the type of bond of HF?
Hydrogen fluoride is a covalently bonded molecule and they have intermolecular hydrogen bonding.
