A covalent bond is _ if atoms in a molecule share their electrons unequally

POLAR

> a covalent bond is formed when two atoms SHARE electrons

(conversely, an ionic bond is when one atom donates an electron to another, more electronegative, atom)

> when there is an UNEVEN distribution of electrons/ electrons are NOT shared equally, then you have a POLAR bond where the CHARGE is not evenly distributed

(resulting in partial positive and negative sides of the molecule.. net dipole)

> POLAR covalent bonds form when there is a greater difference in electronegativity (some atoms have a greater desire to "grab" electrons to fill their octet and become more stable... for example H-F is a polar covalent bond)

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
