There are 13 protons and 14 neutrons in the nucleus of an aluminum atom.

The number of protons is the same as the atomic number and the number of neutrons is just the mass number - atomic number. In a stable atom anyway, there's different isotopes which is where there is a different number of neutrons, but if it doesn't specify then this is what it is.

The number of protons in an atom will always be the same as the atomic number, by which the Periodic Table is organized. So figuring out how many protons an atom has just becomes an exercise at reading the table. In this case, arsenic has an atomic number of 33. If the particle is specifically an atom, then it will be neutral and the number of electrons will balance the number of protons exactly. The number of neutrons will differ depending on the isotope - atoms of the same element with different numbers of neutrons. Although, arsenic has only one isotope found in nature, 75As with 42 neutrons.

How many neutrons are in the nucleus of the isotopes of aluminum-25?

The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.


What element has more neutrons Aluminum or Silicon?

Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 neutrons.


How many neutrons are found in an atom of aluminum-27?

Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons


How many valence electrons protons neutrons and electrons does aluminum have?

The element aluminum has 13 protons. It will have 13 electrons in its neutral state, though aluminum loans out electrons to form bonds. Under these circumstances, it will have 10, 11 or 12 electrons.The only stable isotope of aluminum (aluminum-27), and basically the only one found in nature, has 14 neutrons in it. (There have been, however, investigators who report a trace of Al-26, which has 13 neutrons in it.) We should note that we have synthesized a number of isotopes of aluminum in the lab. Links can be found below for more information.The number of protons in an atom is called the atomic number. Therefor, aluminium has 13 protons. The mass number is the number of protons and neutrons. Therefor, (27-13=14) aluminium has 14 neutrons. The number of protons is equal to the number of electrons, Therefor, aluminium has 13 electrons.


How many neutrons and electrons are there in aluminum?

The aluminum atom has 13 electrons and protons and also 14 neutrons.

How can you find the number of neutrons that are in the nucleus of an atom?

Aluminum is 13 because that is the atomic number (the number of protons). The atomic mass number is the number of protons and neutrons in an atom. In this, you just subtract the number of protons from the mass number. If Aluminum (Al), #13, has a mass number of 27, then it has 14 neutrons. Pretty simple.


What is the element that has 13 protons?

The number of neutrons is irrelevant for determining the element. 13 protons makes it aluminum. (The isotope of aluminum with 13 neutrons is unstable and radioactive, with a half-life of about 720,000 years.)


How many neutrons are in the element aluminum 27?

The number of protons is the atomic number listed on the periodic table. Therefore, the number of protons in aluminum is 13. When no charge is given, the number of protons = the number of electrons, so aluminum-27 also has 13 electrons. The number of neutrons is found using mass number-atomic number. In the name aluminum-27, the 27 indicates the mass number. So the number of neutrons in aluminum-27 is 27-13 = 14.


How many neutrons are in the nucleus of the isotopes of aluminum-25?

The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.


How many neutrons and protons are in aluminum - 27?

13 protons and 14 neutrons


What element has more neutrons Aluminum or Silicon?

Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 neutrons.


Do all aluminum atoms have the same number of protons?

yes, all aluminum atoms have the same number of protons. The number of protons in an atom give it its identity. Isotopes are different atoms of the same element with the same number of protons, but a different number of neutrons.


How many neutrons are found in an atom of aluminum-27?

Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons


How do you determine the number of protons in an atom of aluminum27?

There are 13 protons in an atom of aluminum, regardless of the isotope. If it didn't have 13 protons, it wouldn't be aluminum, it would be something else. There are 14 neutrons in an atom of aluminum 27, its only stable isotope.See the Related Questions for how to count the number of protons, neutrons and electrons in any atom of any element.
