Depends on the pH. The lysine nitrogen is positively charged until pH 9.0 (so at physiological pH it is positively charged).

The net charge is the total amount of charge that the ion will have. So you will find out the charge of each group and add them all together for the net charge.
A sodium atom has a net charge of zero. A sodium ion has a net charge of 1+.
No an electron does not have a net charge of 0, in fact it has a net charge of -1.
The MAJORITY of matter has a net charge of ZERO.
A crystal of salt consists of electrons and positive ions. How does the net charge of the electrons compare with the net charge of the ions
There is no net electrical charge on an "unreacted" atom.
No, h2 does not have a net charge. It is a neutral molecule.
there is no net charge on the capacitor because nomber of positive and negative charge and negetive are equal.
no charge / neutral
because it flows on the direction where the net charge flows. :D
The is no net charge when the carrying wire is at zero.
The net charge of an ionic compound is equivalent to zero.
