The element has 13 protons. So the element is aluminium. It has 15 neutrons (28 - 13 = 15) and the isotope is 13Al28
The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
Carbon is a non metallic element. Mass number of it is 12.
The number of protons for any element is the atomic number. The number of electrons is equal to the number of electrons. To find the number of nuetrons you must subtract the atomic number from the mass number mass number-atomic number= number of nuetrons protons=electron the number of protons in the element aluminum is 13. The number of electrons is 13.
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.)
an element always has as many electrons as protons...... the Atomic Number equals the number of protons. So if your atomic number is 13......you have thirteen protons.....and therefore 13 electrons
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.

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.
Carbon-13 has 6 protons because the element is carbon. Since the atomic number for carbon is 6, it tells us the number of protons. Carbon-13 has 7 neutrons because to get the number of neutrons you subtract the atomic number from the mass number, which is 13.

it is possible for a particular element to have various numbers of neutrons
A substance with 13 protons in each atom is aluminum. With 14 neutrons, it has a mass number of 13 + 14 = 27, and with only 10 electrons is has 13 - 10 = 3 net positive charges. This can be written as 27Al+3.
13 protons an easy way to remember what number of protons an element has is APES. A-atomic number, P-protons, E-electrons, S-same, so the atomic number and the numbers of protons and electrons are the same number
The numbers of protons and electrons in any neutral atom are the same as the atomic number, 13 for aluminum. The number of neutrons varies by isotope and can be found by subtracting the atomic number from the atomic mass number. One isotope is Al-27, in which there are 14 neutrons.
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.)
An aluminum atom has 13 protons, 14 neutrons, and 13 electrons. The number of protons determines the element (which in this case is aluminum), while the sum of protons and neutrons determines the isotope of the element.
