The element with 4 protons and 4 neutrons is beryllium (atomic number 4), normally it would have 4 electrons so it would be electrically neutral, but since it has 3 electrons, it would have a +1 charge.

Beryllium(Be)

However, this form of Beryllium would be extremely rare since Be is usually found with 4 electrons (in the neutral state - Be) or with 2 electrons (in its ionized state - Be2+).
