Module 3: Periodicity Flashcards
(14 cards)
Whats a cation?
It’s a positively charged ion
What’s the d block?
The part of the periodic table where the highest energy electron within a D orbital
What’s electron configuration?
This is the organization of electrons into orbitals and energy levels around the nuclues
Whats first ionization energy?
The removal of one mole ( electron ) from one gaseous atom.
Factors are:
Strength of attraction between electron and nuclues
The nuclear charge
The atomic radius
Exceptions are between sand p subshell.
What’s a giant metallic lattice structure?
The structure of metals, made up of cations and de localized electrons. They are normally insoluble, high melting and Bp points, are good electrical conductors
What’s a giant covalent lattice?
Atoms bonded by strong covalent bonds, are normally insoluble and have high melting and BP points, poor conductors
What’s a group?
Column in the periodic table
What’s the melting point?
The temperature where a solid melts and turns into a liquid.
Order goes:
Giant metallic - giant covalent structures - decrease to simple molecular
Whats metallic bonding?
Strong electrostatic attraction between cations and de localized electrons.
What’s the p-block?
The part on the periodic table where the element has the highest energy level ( electron and nuclues) in the p - orbital
What’s a period?
A row in the periodic table
Whats periodicity?
A repeating trend in physical and chemical properties across the periodic table
What’s the s - block
The electron in the element has the highest value in the s - orbital
Whats successive ionization energies?
The energy needed to remove an electron one by one from a gaseous ion
