What statement about electrons is true?

Two like charges repel each other and unlike charges attract each other. Therefore, the electrons which carry negative charge would repel each other. Therefore, the statement is true.

Who was discovered the electron?


How do you know if electrons are paired?

When there are two electrons in an orbital, the electrons are called an electron pair. Electron pairs are shown with arrows pointing in opposite directions. According to the Pauli Exclusion Principle, two electrons in an orbital will not spin the same way.

Why are paired electrons more stable?

Although electrons repel each other, they can “pair,” which really means they share the same energy level. If this repulsion is less than the attraction that both electrons feel for the protons in a nearby atom, however, they will pair and will be more stable in doing so.

How many paired electrons does sodium have?

two electrons

Does S have two unpaired electrons?

Sulfur has two unpaired electrons in the 3p subshell.১৩ নভেম্বর, ২০১৭

How many paired electrons are in nitrogen?

That means that it has only 3 electrons in the 2p orbitals. Per Hund’s Rule, they will not become paired until each available orbital has one electron in it. Thus, nitrogen contains 3 unpaired electrons – one in each of the available p orbitals.২৪ এপ্রিল, ২০১৮

How many unpaired electrons are present in nitrogen?

Three Unpaired Electrons
