Chapter 1: Structure and Bonding Flashcards
What type of bond is sharing electrons?
Covalent bonding
What type of bond is transferring electrons?
Ionic bonding
What type of bond happens between metals and non metals?
Covalent
What do metals need to do to become stable?
Loose electrons
What do non metals need to do to become stable?
Gain electrons
How do you denote an Ion?
Brackets around the diagram and a + or - symbol, with the number.
What is the structure that Sodium and Chlorine produce called?
A Giant ionic structure. Atoms are organised in a lattice
On the periodic table, a group is…
A vertical column
What is an isotope
A version of an element with a different number of neutrons
How does Hydrogen bond with itself? Why? (1 electron in outer shell)
Hydrogen bonds covalently in pairs to achieve a full outer shell of 2 electrons. H–H
How does chlorine bond with itself? (7 Electrons in outer shell)
Covalent bond. So that each atom has 8 outer electrons
What kind of bond do two metals make?
A metallic bond
How do we describe electrons in metallic structures.
De-localised
How does a metallic bond work?
Many metal atoms loose their outer electrons and they are free to flow between atoms, in a “sea of negative charge”.
