The number of protons in Beryllium is 4.
Beryllium has an atomic number of 4, which indicates the number of protons in its nucleus. Its atomic mass of 9 includes the total number of protons and neutrons in its nucleus. This means that beryllium has 4 protons and usually 5 neutrons.
Beryllium has 4 protons
With 4 protons, 3 electrons, and 5 neutrons, this atom is an isotope of beryllium. The number of protons in an atom determines its identity, so this atom is still beryllium due to its 4 protons. The difference in neutron number makes it an isotope of beryllium.
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.
Beryllium-10 has 4 protons and 4 electrons. Since the atomic number of beryllium is 4, this is how many protons and electrons it has. Beryllium-10 is an isotope, which means it has 6 neutrons, as the total mass number of beryllium-10 is 10.
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
Beryllium has an atomic number of 4, which indicates the number of protons in its nucleus. Its atomic mass of 9 includes the total number of protons and neutrons in its nucleus. This means that beryllium has 4 protons and usually 5 neutrons.

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.
With 4 protons, 3 electrons, and 5 neutrons, this atom is an isotope of beryllium. The number of protons in an atom determines its identity, so this atom is still beryllium due to its 4 protons. The difference in neutron number makes it an isotope of beryllium.
Beryllium
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.
Beryllium-10 has 4 protons and 4 electrons. Since the atomic number of beryllium is 4, this is how many protons and electrons it has. Beryllium-10 is an isotope, which means it has 6 neutrons, as the total mass number of beryllium-10 is 10.
Beryllium has four protons. 4 because that is atomic number
