In an ionic bond, one atom all its
electrons.
This leaves behind a filled
shell. Losing electrons
creates a
charge (less electrons than protons). These
types of atoms are called a .

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
