Boron has 5 protons in an atom. The atomic number is the same number as the amount of protons.
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 because the atomic number represents the number of protons in an atom.
An atom's atomic number tells us the number of protons it has. Boron's atomic number is 5. Thus, boron has 5 protons.
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.
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. In this case, with 5 protons and 6 neutrons, the mass number of the boron atom would be 5 + 6 = 11.
A boron ion typically has 5 protons. Boron has an atomic number of 5, which represents the number of protons in a neutral boron atom. Since ions have a positive or negative charge, the number of protons remains the same, but the number of electrons differs to give the ion its charge.
The mass number of an atom is the total number of protons and neutrons in its nucleus. Therefore, the mass number of boron with 5 protons and 6 neutrons is 11.
Atomic number = 5So there are 5 electronsAtomic number=protons=electrons
A neutral boron atom has 5 electrons. On the periodic table, the atomic number of boron is 5. This means that all boron atoms have 5 protons in their nuclei. Protons are positively charged, and electrons are negatively charged, therefore, a neutral boron atom has 5 protons and 5 electrons.
Boron has an atomic number of 5, which means that it has 5 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons surrounding the nucleus. Therefore, a boron atom has 5 electrons to balance the 5 protons.
I'm almost positive the protons always tell you the identification of an element on the periodic chart... the atom with 6 protons is Carbon a non metal but if electrons are 5 then it must be carbon cation C+.
