What is the atomic number of an atom that has 5 protons 6 neutrons and 5 electrons?
And since the atomic number of Boron is 5, the atomic number of the ion of Boron is also 5. Boron with an electron configuration of 2, 3 will lose its three valence electrons and becomes 3+. The atomic number is strictly defined as the number of protons in an atom. So in this case, the answer is 5.
What is the atomic number of an atom with 5 protons and 6 neutrons?
Answer : (a) The nucleus of an atom has 5 protons and 6 neutrons then the atomic no. 5. (b) The nucleus of an atom has 5 protons and 6 neutrons then the mass no. will be 6+5 = 11.
What element has 5 protons 6 neutrons and a charge of 3+?
Atomic Number
Name | Protons | Electrons |
---|---|---|
Lithium | 3 | 3 |
Beryllium | 4 | 4 |
Boron | 5 | 5 |
Carbon | 6 | 6 |
How do you find the atomic number of an ion?
The proton number is the atomic number of the element, while the electron number is the atomic number minus the charge. A negatively-charged ion or anion has more electrons than protons. Again, the number of protons is the atomic number. The number of electrons is the atomic number added to the charge.

What isotope has 6 protons 5 neutrons and 6 electrons?
Carbon-12
Carbon-12 is of particular importance in its use as the standard from which atomic masses of all nuclides are measured, thus, its atomic mass is exactly 12 daltons by definition. Carbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons.
What is the charge of Group 6?

What is the atomic number of a positively charged ion?
This number is the atomic number of the element. A positively-charged ion or cation has more protons than electrons. The proton number is the atomic number of the element, while the electron number is the atomic number minus the charge.
Which ion has more electrons than protons?
A negatively-charged ion or anion has more electrons than protons. Again, the number of protons is the atomic number. The number of electrons is the atomic number added to the charge.
How do you find the number of protons and electrons?
The proton number is the atomic number of the element, while the electron number is the atomic number minus the charge. A negatively-charged ion or anion has more electrons than protons. Again, the number of protons is the atomic number. The number of electrons is the atomic number added to the charge.
How many protons and electrons are in the scandium ion?
The atomic number is 21, which means that scandium has 21 protons. While a neutral atom for scandium would have the same number of electrons as protons, the ion is shown to have a +3 charge. This means it has 3 fewer electrons than the neutral atom or 21 – 3 = 18 electrons. The Sc 3+ ion contains 21 protons and 18 electrons.
