Exploring Pseudo Noble Gas Electron Configurations

What is the primary reason for the stability of noble gas electron configurations?

• They have a high number of protons.

• Their valence shells are completely filled.

• Their electrons are in the lowest energy state.

• They have a low number of neutrons.

Why are noble gases inert?

• They have a high atomic mass.

• Their valence shells are completely filled.

• Their electrons are in the highest energy state.

• They have a low atomic number.

How do s block and p block elements achieve stability?

• By gaining or losing electrons to attain the nearest noble gas configuration.

• By gaining or losing neutrons.

• By changing their atomic number.

• By gaining or losing protons.

In transition metals, which orbitals are filled first according to the Aufbau principle?

• f orbitals

• s orbitals

• p orbitals

• d orbitals

Why do transition metals often lose their outermost s electrons first?

• To fill their d orbitals.

• To decrease their atomic number.

• To increase their atomic mass.

• To attain a pseudo noble gas electron configuration.

What is the electron configuration of a silver atom before ionization?

What happens to the electron configuration of silver when it ionizes?

• It loses the lone 5s electron.

• It gains an electron in the 4d orbital.

• It gains an electron in the 5s orbital.

• It loses an electron in the 4d orbital.

What is a pseudo noble gas electron configuration?

• A configuration with 10 electrons in the outermost shell.

• A configuration with 2 electrons in the outermost shell.

• A configuration with 8 electrons in the outermost shell.

• A configuration with 18 electrons in the outermost shell.

Which of the following ions has a pseudo noble gas electron configuration?

• Cl-

• Na+

• Zn2+

• O2-

How does pseudo noble gas electron configuration explain the common oxidation states of transition metals?

• By demonstrating that they have a high atomic mass.

• By indicating that they have a full valence shell with 18 electrons.

• By proving that they have a low atomic number.

• By showing that they have incomplete d orbitals.
