The atomic number of an element is equal to the number of protons in its nucleus. The atomic weight is the average mass of an element's isotopes, taking into account their relative abundance. Both the atomic number and weight can be found on the periodic table for each element.
you add the number of protons (the atomic number) to the number of neutrons
No, the atomic number is the number of protons and electrons in a given element. The atomic weight is the weighted average of the isotopes in a natural environment.
"np" on the periodic table usually stands for the number of electrons in the outermost energy level of an element. It is used to represent the valence electrons of an element.
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
100% sure its weight
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
The atomic number of an element is equal to the number of protons in its nucleus. The atomic weight is the average mass of an element's isotopes, taking into account their relative abundance. Both the atomic number and weight can be found on the periodic table for each element.
The numbers on the periodic table represent the atomic number, which is the number of protons in an atom's nucleus. The letters represent the chemical symbol of each element.
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
The atomic number represents the number of protons in an atom's nucleus, which determines the element's identity. Atomic weight, or atomic mass, is the average weight of an element's isotopes, taking into account their abundance in nature. Atomic weight is a weighted average of the different isotopes for each element.
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
