Metallic Bonds
100
The combining of atoms to form molecules or ionic compounds.
What is chemical bonding?
100
Metallic bonding allows metals to conduct ___________.
electric current
100
The attractive force between oppositely charged ions, which form when electrons are transferred from one atom to another.
What is an ionic bond?
100
A bond formed when atoms share one or more pairs of electrons.
What is a covalent bond?
100
A bind formed by the attraction between positively charged metal ions and the electrons around them.
What is metallic bond?
200
An interaction that holds atoms or ions together.
What is a chemical bond?
200
What causes covalent bonds?
Atoms sharing electrons that form a full outer cloud of them.
200
Gain an electron.
How does an atom become negatively charged?
200
A molecule.
What is formed when there is a covalent bond?
200
They are like in a sea of them.
how are the electrons like in metallic bonds?
300
An electron that is found in the outermost sell of an atom and that determines the atom's chemical properties.
What is valence electron?
300
What is the thing used to create chemical bonds?
Electrons
300
Why is sodium chloride safe to eat, when they are made of two deadly elements?
When chemicals bond, they for completely new elements.
300
They are shared.
What are the electrons like in a molecule or covalent bond?
300
Why is metal bendable without breaking?
The electrons are in a sea of them so they are kept in a piece but a different shape.
400
Five valence electrons.
What is the amount of valence electrons in group 15.
400
What happens in ionic bonds?
They have their electrons taken away or get an extra few and they become charged. Then they attract.
400
The regular pattern in which crystal is arranged. Makes table salt into a solid.
What is crystal lattice?
400
They are the simplest molecules yet some are the most important.
What are diatomic molecules?
400
Why are metallic bonds good at conducting electricity?
The electrons are free to move and they are in a sea that carries the current.
500
The amount of valence electrons of an atom determines.
What determines if an atom will bond?
500
How are electrons used in covalent bonds?
They are shared!
500
What are four properties of ionic compounds?
Britle and high soluble, with high melting and boiling points.
500
Electrons are shared when put together and they can make a full valence electron shell.
What is covalent bonding?
500
Metals are malleable. True or false?
True!
