what is an ionic bond?
when atoms transfer electrons (2 or more atoms)
What is a covalent bond?
bond that results between nonmetallic elements that share electrons, forming a molecule
What kind of an atom makes up covalent bonds?
non metal atoms
what kind of atoms make up an ionic bond?
metals
what is a cation and what results in it?
a positively charged ion
results a atom loses one or more electrons
what is a anion and what results in it?
an atom or molecule with a net negative charge
resulting from gaining more electrons than protons
What are the properties of metallic bonds?
malleable
ductile- (can be made into wires)
conducts electrical and thermal energy
what are the properties of ionic compounds
high melting/boiling points hardness, brittleness
What are the properties of covalent compounds?
low melting and boiling points, poor electrical conductivity and not soluble in water
What is an alloy
a solution of two metals mixed together
what range of electronegativity results in mostly covalent bonds
between 0 and 0.5
What range of electronegativity results in mostly polar covalent bonds?
between 0.5 and 2
What range of electronegativity results in mostly ionic bonds
greater than 2
How do metallic bonds share electrons?
sea of electrons
