Science Chapter 1 Electron and Chemical Bonding

Chemical bonding
joining of atoms to form new substances. properties of new are different from the original elements
chemical bond
force of attraction that holds 2 atoms together
valence electrons
electrons in the outermost energy level of an atom
ionic bond
the force of attraction between oppositely charged ions
charged particles that form during chemical changes when one or more valence electrons transfer from atom to another
crystal lattice
the ions that make up an ionic compound are bonded in a repeating 3 D pattern
how does an atom become a negative ion
it gains an electron
what are 2 properties of ionic compounds
brittle, form crystal lattice
covalent bonds
force of attraction between the nuclei of atoms and the electrons shared by the atoms
neutral group of atoms held together by covalent bonds
diatomic molecules
simplest molecules. consist of two atoms bonded together.
metallic bonds
the force of attraction between a positively charged metal ion and electrons in a metal
the ability to drawn into wires
the ability to be hammered into sheets
what happens to electrons in covalent bonds
they are shared by the atoms
what type of element is most likely to form a covalent bond
whos the best science teacher in 8th grade

The force of attraction that holds two atoms together is a
chemical bond
charged particles that form when atoms transfer electrons
The Force of attraction between the nuclei of atoms and shared electrons is a(n)
covalent bond
Electrons free to move throughout a material are associated with a
metallic bond
shared electrons are associated with what type of bond
covalent bond
Which element has a full outermost energy level containing only two electrons
Helium (He)
The properties of ductility and malleability are associated with which type of bond
In which area of the periodic table do you find elements whose atoms easily gain electrons

Covalent non metals share
Metallic metals swim free to move
