The number of protons.
Carbon = a Z number of 6.
Hydrogen = a Z number of 1
Oxygen = a Z number of 8.
And so on. Just read it off the Periodic Table.
The symbol for an element is typically written as [A-Z][a-z][number], where A is the element's atomic number, Z is the element's chemical symbol, and the number represents the sum of protons and neutrons (called mass number). So, for 12 protons, 10 electrons, and 12 neutrons, the symbol would be Mg.
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is represented by the symbol "Z" on the periodic table. The atomic number determines the element's identity and its unique properties.
A = mass number z = atomic number so this one is a Ni isotope with a mass of 64
Z is atomic number, so from the periodic table, you can see that this is the element krypton, Kr. You can also see that this element is in Group 18 (VIIIA), which is the noble gases group.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
The atomic number of an element represents the number of protons in an atom's nucleus. The letter "Z" is often used to symbolize the atomic number of an element in chemistry. The specific atomic number of an element would depend on which element is being referenced.
Z means the number of protons in an atom of an element, which is the element's atomic number.
A is mass number of the element (also the number of protons and neutrons) and Z is the atomic number of the element (also the number of protons)
Z is the atomic number in Chemistry and Physics.
the atomic number of an element
Atomic number(z) of an element is the number of protons present in an atom.z = p(protons)
The symbol for an element is typically written as [A-Z][a-z][number], where A is the element's atomic number, Z is the element's chemical symbol, and the number represents the sum of protons and neutrons (called mass number). So, for 12 protons, 10 electrons, and 12 neutrons, the symbol would be Mg.
There is no element with the abbreviation "Hz". There's He (helium) with Z = 2, Ho (holmium) with Z = 67, Hf (hafnium) with Z = 72, and Hs (hassium) with Z = 108.Hz is the abbreviation for "hertz" in physics, but that's not a chemical element.
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is represented by the symbol "Z" on the periodic table. The atomic number determines the element's identity and its unique properties.
Z(Atomic number) IS the number of protons in a nucleus.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
The ATOMIC NUMBER (Z) gives the position of an element in the Periodic Table. It also indicates the number of protons and electrons in an atom of a given element. Taking two examples;- Z = 1 ; Hydrogen ; No. of protons = 1, No of electrons = 1 Z = 6 ; Carbon ; No. of protons = 6, No of electrons = 6
