Electronic Configuration

What is an orbital?

• A region that holds up to 2 electrons, with opposite spin.

• A region that holds up to 6 electrons, with opposite spin

• A region that holds up to 10 electrons, with opposite spin.

• A region that holds up to 14 electrons, with opposite spin.

Describe and sketch the shapes of the s and p orbitals

• s- and p-orbitals are spherical

• s- and p-orbitals are dumb-bell

• s-orbital is spherical and p-orbital is dumb-bell

• s-orbital is dumb-bell and p-orbital is spherical

What is a subshell?

• A division of electron shells into different energy

• A division of electron shells into different orbitals

• A division of electron shells into different shape

• A division of electron shells into different charge

What is meant by the term first ionisation energy?

• The energy required to remove an electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ atoms.

• The energy required to remove an electron from each atom in one mole of liquid atoms to form one mole of gaseous 1+ ions.

• The energy required to remove an electron from each atom in one mole of solid atoms to form one mole of gaseous 1+ ions.

• The energy required to remove an electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ ions.

"in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy level before occupying higher-energy levels"
The statement above is ............ principle

• Aufbau

• Hund

• Pauli

• Avogadro
