Which of the following is the difference between covalent and ionic bonds? a. electrons are transferred to form covalent bonds b. covalent bonds are weaker than ionic bonds c. ionic bonds are weaker than covalent bonds d. electrons are shared to form ionic bonds

electrons are shared in a covalent bond.

just took the test ;)

b. covalent bonds are weaker than ionic bonds

Explanation:

Covalent bonds are formed when valence electrons are shared between two participating ions.

Ionic bonds are formed when electrons are transferred from a donor ion to an acceptor element during a reaction involving the two. This results in one ion being negatively charged and the other being positively charged

The opposing force between the two ions in ionic bonds creates a coulombic force which holds together and makes ionic bonds stronger than covalent bonds.

Hence, the correct option is b.

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
