How many neutrons and electrons does berylluim?

Answer 1

neutrons in berylium are 5 because Atomic Mass - 9 Atomic number - 4 number of neutrons = Atomic mass - Atomic number = 9 - 4 = 5 neutrons = = berylium is metal = no berylium is not a true metal most of its properties are similar to the non metals.....

Answer 2

To find the number of neutrons in an isotope of beryllium, you would subtract the atomic number (4) from the atomic mass number. Almost all natural beryllium is of the isotope 9Be or beryllium-9, which has 4 protons and 5 neutrons in the nucleus.

For other elements, you would need the atomic mass number for the specific isotope to determine the number of neutrons, which can vary.

Answer 3

5 neutrons

4 electrons
