FranBeryllium has 4 protons and electrons; the number of neutrons is variable, depending on the isotope.
Number of neutrons = Atomic Mass of the isotope - Atomic number (for Be is 4)
To answer this, we need to look at a Periodic Table. From there, we see that beryllium's atomic number is 4. That means that beryllium has 4 protons.

How many protons are in the nucleus of an atom?
The number of protons in the nucleus of an atom is equal to the atomic number of the element.
How many particles are in the nucleus of an atom of xenon?
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
How many proton does the atom have?
There are 9 protons in the element fluorine.
What are two differences between the nucleus of an atom and the electrons of an atom?
The nucleus of an atom has a positive electrical charge, the electrons have a negative electrical charge, and the nucleus is thousands of times heavier than the electrons (the exact ratio of weight varies, because although there are always as many protons as electrons, in a neutral atom, the number of neutrons varies).
How many protons in Aragon atom?
An argon atom has 18 protons.
