If this atom has 43 electron it must have 43 protons to be a neutral atom of no charge.
There are similar number of electrons and protons. it has 15 electrons and protons.
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
Manganese (Mn) has an atomic number of 25, which means it has 25 protons and, in a neutral atom, 25 electrons. The most common isotope of manganese has a mass number of 55, which means it has 30 neutrons (55 - 25 = 30). Therefore, a neutral manganese atom contains 25 protons, 30 neutrons, and 25 electrons.
There are 19 protons in the potassium atom.
5 electrons because no. of protons= no. of electrons
An electrically neutral atom of boron has 5 electrons. This is because the number of electrons in a neutral atom equals the number of protons, and boron has an atomic number of 5, indicating it has 5 protons. Therefore, to maintain electrical neutrality, it also has 5 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.
5 electrons because no. of protons= no. of electrons
An atom of boron-10 (10B) has 5 electrons. The atomic number of boron is 5, indicating the number of protons and electrons in a neutral atom.
Boron has 5 protons in an atom. The atomic number is the same number as the amount of protons.
5 protons in one atom of boron. look at the periodic table.
5. If it is more or less than 5 protons then it is not boron.
All you need is the atomic number, which gives the number of protons, in this case, 5. In any neutral atom the number of electrons is the same as the number of protons. So any neutral boron atom will have 5 electrons.
Boron's atomic number is 5. Thus, it has 5 protons per atom. To be electrically neutral then, it must also have 5 electrons per atom.
Boron has 5 protons because the atomic number represents the number of protons in an atom.
5 protons, 5 electrons and 6 neutrons :)
