5
Boron's atomic number is 5. So there are 5 protons and 5 electrons. In Boron-10, there are 5 neutrons (10 - 5 = 5)
The atomic number of boron (5) indicates the number of protons in the nucleus of a boron atom. This means that a boron atom has 5 protons. Since atoms are electrically neutral, it also tells us that a boron atom has 5 electrons to balance the positive charge of the protons.
Boron has 5 protons in an atom. The atomic number is the same number as the amount of protons.
Boron has 5 protons because the atomic number represents the number of protons in an atom.
Atomic number = 5So there are 5 electronsAtomic number=protons=electrons
The symbol of a boron atom is "B", and the number of electrons in a neutral atom is the same as the number of protons, which equals the atomic number of boron: 5.
mass number
Boron's atomic number is 5. So there are 5 protons and 5 electrons. In Boron-10, there are 5 neutrons (10 - 5 = 5)
mass number = protons + nuetrons
The atomic number of boron (5) indicates the number of protons in the nucleus of a boron atom. This means that a boron atom has 5 protons. Since atoms are electrically neutral, it also tells us that a boron atom has 5 electrons to balance the positive charge of the protons.
The Mass Number.
Number of Neutrons = Mass number - Atomic Number
Isotope.
Boron has 5 protons in an atom. The atomic number is the same number as the amount of protons.
there are 12 nuetrons in an atom of magnesium
Boron has 5 protons because the atomic number represents the number of protons in an atom.
