covalent bonds
how would you decide what a poor covalent bond is?
electrons are shared unequally between two atoms due to the difference in electronegativity
how does the difference in electronegativity in an ionic bond develop it's structure
this would lead to a stronger bond due to the high difference in electro negativity
how does the "sea of electrons" result in the metals being conductive?
valence electrons are loosely spread that are free to move allowing an electric current to occur
what is the name of this ionic formula? NaCL
Sodium chloride
what is the chemical formula of this covalent compound: Phosphorus tri chloride
PCL3
how would increasing the shared electrons in a covalent bond affect the strength of the bond?
adding more electrons creating a single, double, triple bond can increase the stability of the bond making it harder to break
what is the significance of the lattice crystal in ionic bonds regarding the melting points and structure?
the lattice crystals result in high melting and boiling points, and a specific arranged pattern due to ions of opposite charges
what is the significance of the structure of metallic bonds?
lattice of positively charged ions which are surrounded by a sea of detached electrons
what is the name of this ionic formula? CaCO3
Calcium carbonate
what is the chemical formula of this covalent compound: Dioxygen Diflouride
O2F2
what are the types of covalent bonds and how do they form?
single, double, and triple form when there are shared electrons in a covalent bond
how does the transfer of a nonmetal and a metal result in ionic bonds, how does this affect the stability?
the metal is a positively charged ion, and the nonmetal is a negatively charged ion which causes a strong bond between them
how do metallic bonds become so malleable?
the free moving electrons within the nuclei allow the metal to become malleable
what is the name of this ionic formula?
KI
Potassium iodide
what is the chemical formula of this covalent compound: Nitrogen dioxide
NO2
what is a covalent bond and how is it different from an ionic bond?
atoms are sharing electrons in covalent bonds which are usually formed between nonmetals, whilst ionic bonds transfer electrons and this occurs between a metal and a nonmetal
in ionic bonds why are prefixes not used?
prefixes are only used in covalent bonds to indicate the number of atoms of each element that are present
due to the metallic bond do they result in high or low melting points?
high melting point due to the cations
what is the name of this covalent formula? CH4
Methane

MgSO4
model this named compound as a chemical formula Dinitrogen Tetraoxide
N2O4
what is the chemical formula of this ionic compound name: Sodium fluoride
NaF
what is an example of a metallic bond?
magnesium
what is the name of this covalent formula? H2O
water
what is the chemical formula of this ionic compound: Ammonium phosphate
