The atomic number of beryllium is 4. The atomic number of an atom says how many protons are in that atom. In an unionized atom, the protons and electrons are the same amount. Beryllium (unionized) has 4 electrons and 4 protons.
4 electrons 4 protons
Beryllium has 4 protons
A neutral atom of beryllium has 4 electrons. In a neutral atom, the numbers of electrons and protons are equal. An element's atomic number is the number of protons.
Since the mass number is protons plus neutrons, it would have 5 neutrons.
The atomic/proton no. of beryllium is 3. Thus the number of protons is 3.
The atomic number of Beryllium is four, which is also the number of protons.
Be, or beryllium, has 4 protons, which is the same number as its atomic number

The atomic number of an atom tells you how many protons that atom has. Beryllium's atomic number is 4. That means that, regardless of how many neutrons a given isotope of beryllium may have, it will always have 4 protons.
The atomic number of beryllium is 4. The atomic number of an atom says how many protons are in that atom. In an unionized atom, the protons and electrons are the same amount. Beryllium (unionized) has 4 electrons and 4 protons.
4 electrons 4 protons
Beryllium has 4 protons
The number of protons determines the atomic number. Since there are for protons, the atomic number is four, and the element is beryllium, symbol Be. The atomic mass number is the number of protons plus neutrons, so in this case it is 9. There are an equal number of protons and neutrons, so there is not charge. The symbol looks like this:94Be
Beryllium has four protons. 4 because that is atomic number
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.
A neutral atom of beryllium has 4 electrons. In a neutral atom, the numbers of electrons and protons are equal. An element's atomic number is the number of protons.
