Aluminum (Al)
Aluminum!
An atom with six protons in the nucleus is a carbon element.
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.
It is equal to the no. of electrons in the atom. It is called the atomic number.
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons. Isotopes of the same element have the same number of protons and electrons, which is the atomic number of the element.
Each atom of an element has the same number of protons which is unique for that particular element ( = atom number in the periodic system)
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
The atomic number of a chemical element is equal to the numbers of protons in the atomic nucleus; as an example: aluminium, with the atomic number 13 has also 13 protons. All the isotopes of an element has the same number of protons.
An atom with six protons in the nucleus is a carbon element.
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.
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.
The type of atom is now different from what it was. (It has a new identity.)
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.
In an atom, the number of protons is the same number as the atomic number.
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.
Aluminium is a natural chemical element; the atom contain 13 protons, 13 electrons and 14 neutrons.
The element mercury has 80 protons.
It is equal to the no. of electrons in the atom. It is called the atomic number.
