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.
What else can I help you with?
How do you determine the number of electrons in an atom?
The number of electrons in an atom is determined by the atomic number of the element, which is the same as the number of protons in the nucleus. Electrons are negatively charged particles that balance the positive charge of protons in an atom.
How many protons are in the nucleus of an atom?
The number of protons in the nucleus of an atom is equal to the atomic number of the element.
How are subatomic particles responsible for an atom's characteristics?
Protons determine what the element is. Although the number of electrons and protons are the same(since the atom in electrically neutral), the number of electrons is more closely tied to the chemical properties than the number of protons, especially in reactions.
What information about the subatomic makeup of an atom is given by the atomic number?
The atomic number of an atom gives the number of protons in its nucleus, which also determines its unique identity as an element. It also indirectly gives the number of electrons in a neutral atom, as the number of protons is balanced by the number of electrons in the atom.
How many protons does a lithium atom have?
Based on the atomic number of lithium there are three protons in a lithium atom.
How do you determine the number of neutrons in an atom of aluminum27?
there are 24 and no it isn't too high
What do the protons of the nucleus of an atom determine?
Number of protons or the atomic number of an atom determines what is the element.
What does the number of protons in a nucleaus determine of an atom?
The number of protons in the nucleus of an atom determines the atomic number of the element to which the atom belongs.
How are the number of protons an important aspect of the atom?
the number of protons determine what the substance is. if the number of protons in an atom change, the substance made of that atom changes too.
What determine the atomic number of atom?
The number of protons
What do protons determine about an element?
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
What determine the charge of an atom?
It depends on the number of electrons and protons the charge of an atom depends on the number of electrons and the number of protons
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
What does the mass number determine?
The Number Of Protons & Neutrons In An Atom.
Is the atomic number determine by the number protons in an atom?
yes...
What number is used to determine how many electrons are in a neutral atom?
The number used to determine how many electrons are in a neutral atom is the atomic number, which is the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is equal to the number of protons, thus balancing out the positive charge of the protons with the negative charge of the electrons.
