Beryllium
To figure this out:
The atomic number of an element is the number of protons the element has in the nucleus. Using this knowledge you can figure out which element has the atomic number of four, which in this case is Beryllium.

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+).
As you already know the atom consists of protons, neutron and eletrons. The number of protons determins which chemical element it is, and on the periodic table of elements, we can see that the next element after lithium is beryllium.-An atom with 3 protons, 3 neutrons, and 3 electrons.- An atom with 3 protons, 5 neutrons, and 3 electrons
No, the number of protons and neutrons are not always equal in an atom. The number of protons determines the element's identity, while the number of neutrons can vary, leading to different isotopes of the same element.
Fluorine is an element. Its atoms are made of basically 3 fundamental particles (as is an atom of every other element just with different proportions) called electrons, protons and neutrons. Fluorine itself is a pure substance and contains no other particles except Fluorine atoms.
Chlorine atoms consist of 17 protons, 17 electrons, and typically 18 neutrons in its most common isotope, chlorine-35.
A lithium atom contains three protons, three electrons, and usually four neutrons in its nucleus. The electrons occupy energy levels around the nucleus in a specific configuration.
