covalent bonds Flashcards
1
Q
Covalent bonds
A
form between atoms with similar electronegativity
electrons are attracted to atoms equally and are shared between the two, forming a molecule
2
Q
electrostatic force
A
force between the electrons and protons in each nucleus
3
Q
single covalent bond
A
when atoms share 1 pair of electrons
4
Q
Lewis structure - covalent bonds
A
determine the total number of valence electrons
arrange elements
fill in electrons, start with bonds first then add lone pairs
if not enough electrons to fill all octets create double or triple bonds
4
Q
double covalent bond
A
when atoms share 2 pairs of electrons
5
Q
triple covalent bond
A
when atoms share 3 pairs of electrons
6
Q
RULES WITH LEWIS STRUCTURE AND COVALENT BONDS
A
hydrogen, H, full at 2e
beryllium, Be, full at 4e
boron, B, full at 6e
