The atomic number is equal to the number of protons [or electrons, since P and E are also equal]
So the answer is 3
It is equal to the no. of electrons in the atom. It is called the atomic number.
The atomic number of an element is equal to the number of protons in the nucleus of that element.
The atomic number of an atom is equivalent to the number of protons in its nucleus.
The number of protons in an atom is its atomic number.
The atomic number of an atom is determined by the number of protons it has.
The number of protons in a nucleus of an atom constitutes the proton number or atomic number of that element and is denoted as Z. For example, helium has atomic mass of 4 and atomic number of 2, thereby having two protons.
The atomic number IS the number of protons in the atom's nucleus.
The atomic number is the number of protons in an atom's nucleus.
The amount of protons in an atom is its atomic number
Directly. An atom's atomic number IS the number of protons in the nucleus.
The answer is the atomic numberIn an atom: Number of protons = number of electrons = element ATOMIC NUMBER
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
