What is the relationship between the principal quantum number (n) and energy of an electron?

Back

An electron with a higher principal quantum number (n) has more energy than an electron with a lower n.

Front

What is a representative element?

Back

Representative elements are elements in groups 1, 2, and 13-18 of the periodic table, which include metals, nonmetals, and metalloids.

Front

What is density?

Back

Density is defined as the mass of an object divided by its volume (Density = Mass/Volume).

Front

How many orbitals are in the d sublevel?

Back

There are 5 orbitals in the d sublevel.

Front

Which element has the largest ionization energy among F, He, Sr, Ra, and Be?

Back

Fluorine (F) has the largest ionization energy.

Front

What does the principal quantum number (n) indicate?

Back

The principal quantum number (n) indicates the energy level of an electron in an atom.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the significance of the d sublevel in electron configuration?

Back

The d sublevel can hold a maximum of 10 electrons and is important for transition metals.

Front

What is the difference between stability and energy in the context of electrons?

Back

Stability refers to how likely an electron is to remain in its current state, while energy refers to the amount of energy the electron possesses.

Front

What is the trend of ionization energy across a period in the periodic table?

Back

Ionization energy generally increases across a period from left to right.
