The type of bond where valence electrons are TRANSFERRED is called: Isotope Ionic Covalent Hydrogen

## Step 1<br />The problem is asking us to identify the type of bond where valence electrons are transferred from one atom to another. This is a characteristic of an ionic bond.<br /><br />## Step 2<br />In an ionic bond, one atom donates one or more electrons to another atom. This results in the formation of positively charged ions (cation) and negatively charged ions (anion). The positive and negative charges of the ions attract each other, forming an ionic bond.<br /><br />## Step 3<br />The other options provided, Isotope, Covalent, and Hydrogen, do not fit the description given in the problem. Isotopes are variants of a particular chemical element which differ in neutron number, and hence in nucleon number. Covalent bonds involve the sharing of electron pairs between atoms, and Hydrogen bonds are a type of bond that forms between a hydrogen atom and an electronegative atom.
