Question

if an atom has electrons that spin in opposite directions, their magnetic fields A. add to make a larger field B. attract other atoms C. cancel out D. alternate directions

Answer 1

If an atom has electrons that spin in opposite directions, their magnetic fields cancel out. Therefore, the correct answer is C.

Step-by-step explanation:

When two electrons with opposite spins are present in the same orbital, their magnetic fields are oriented in opposite directions. This causes the magnetic fields to cancel out, resulting in a net magnetic field of zero. This phenomenon is known as the Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers, including their spin. This principle helps to explain many of the properties and behaviors of atoms, including their magnetic properties.

Answer 2

C. cancel out

Step-by-step explanation:

Electrons have a property known as "spin," which can be thought of as a tiny magnetic field. When two electrons in an atom have opposite spins, their magnetic fields cancel out each other, resulting in a net magnetic field of zero. This is known as diamagnetism, and it causes a substance to be repelled by a magnetic field.

Therefore, when electrons in an atom spin in opposite directions, their magnetic fields cancel out, and there is no net magnetic field produced.
