Atoms, Ions, and Compounds + Electrons and Bonding (F6examonly)

Question 1

What are isotopes?

Answer 1

atoms of the same element with the same number of electrons and protons, but different number of neutrons, resulting in different atomic masses

Question 2

What is the relative mass of an electron compared to protons and neutrons?

Answer 2

1/1836

Question 3

What are subshells?

Answer 3

orbitals of the same type grouped together within a shell

Question 4

What is an atomic orbital?

Answer 4

• a region around the nucleus that can hold up to 2 electrons with opposite spins
• this region is where there is a high probability of an electron being there

Question 5

What is the shape of an s-orbital?

Answer 5

sphere

Question 6

What is the shape on an p-orbital?

Answer 6

dumbbell

Question 7

What is a covalent bond?

Answer 7

the strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms

Question 7

What are dative covalent bonds?

Answer 7

a covalent bond where the shared pair of electrons are donated from one of the atoms only - both electrons in the shared pair originate from the same donor atom
