Bonding Flashcards
What is an atom?
The smallest part of an element, containing protons, neutrons and electrons
What is an ion?
A charged atom either positive or negative
What is an ionic bond?
A chemical bond formed between oppositely charged ions
What are covalent bonds?
The bonds formed when atoms join together by sharing electrons
What is metallic bonding?
The bonding found in metals, where the atoms donate electrons to give a ‘sea’ of electrons and metal ions
What does malleable mean?
Capable of being hammered into shapes without smashing - a property of metals
What is electrostatic force?
The force of attraction between oppositely charged ions in an ionic bond
What are transition metals?
The large block of metallic elements in the middle of the periodic table
What is a smart alloy?
An alloy, which returns to its original shape when it is heated
What does ductile mean?
Able to be pulled into wires
What is a cation?
A positively charged metal ion
What is an anion?
A negatively charged metal ion
What is an alloy?
A metallic substance formed by combining two or more metals
What are delocalised electrons?
Electrons, which are free to move in a ‘sea’ of electrons in the metal structure
What do metals form when they lose electrons?
Positive ions
