28Si
Silicon-14
The nuclear symbol and hyphen notation for 26 protons and 30 neutrons is 26Fe, iron-56. A proton is a particle that has a positive charge and is found in the nucleus of an atom.
Helium is a non metal element. Mass number of it is 4.
If an isotope has an atomic number of 8 and a mass number of 16 - IT IS OXYGEN
An atomic number of 2 makes the element helium; therefore, the notation is He-4.
oxygen-16
oxygen
Sodium is a metal element. Atomic mass number of it is 23.
Calcium is a metal element. Atomic mass of it is 40.
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
Platinum is a metal element. Atomic mass of it is 195.08.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
Sodium is a metal element. Atomic mass number of it is 23.
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
the atomic mass is the number of protons and neutrons in an atom of an element and the atomic number is the number of protons of an atom of an element.
Calcium is a metal element. Atomic mass of it is 40.
The Atomic Mass is equal to the number of protons and electrons that an element has.
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
Sulfur- Element Number 16 on the Periodic Table of Elements
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
Titanium is a metal element. Atomic number of it is 22.
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
Aluminium is a metal element. Atomic number of it is 13.
