UNIT 1-ATOMIC STRUCTURE🤎 Flashcards
Explain the structure of an atom (give 3 particles in an atom, their location, relative charge and their mass, describe the distribution of mass and charge within an atom
❤️
define atomic number and mass number, give one other name for atomic and mass number
❤️
show the behaviour of protons, neutrons and electrons in an electric field
❤️
state and explain the trend of atomic radius across a period and down a group
❤️
what is an isotope using keywords? draw and label parts of an isotopic symbol (2)
❤️
state and explain two characteristics of isotopes
❤️
differentiate between shells, sub-shells, orbitals, principal quantum number and ground state (limited to electronic configuration)
❤️
state the number of orbitals making up the three types of sub-shells and state the number of electrons that can fill the sub-shells
❤️
order the sub-shells D,F,P,S in order of increasing energy, list the sub-shells from 1s to 5s in order of increasing energy
❤️
explain the variation the way the electronic configuration of elements is written for the first 36 elements
❤️
draw the distribution of electrons in different sub-shells in chlorine using boxes
❤️
sketch and label the shape of an s orbital and different p orbitals
❤️
define a free radical
❤️
define the term first ionisation energy, use equations to represent first, second and third ionisation energies for calcium, explain the reason for the variation in the first, second and third ionisation energies of calcium
❤️
explain the trend in ionisation energies across a period and down a group
❤️
