How do you get the atomic number and weight?
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.
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
Is the atomic number and the atomic weight the same?
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.
What element has the atomic number of 168?
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.
What does np stand for on the periodic table of elemnts?
Np stands for the element neptunium.its atomic number is93 and atomic weight is 273
What does the atomical number represent?
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
What does the number below each element's symbol represent?
100% sure its weight
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
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.
How do you get the atomic number and weight?
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.
Does atomic weight is same with atomic number?
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.
What do the numbers and letters in the periodic table represent?
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
What is the difference between the atomic number and the atomic weight of the known elements as listed on the periodic table?
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.
What is a atomic number in a 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.
What is it's atomic weight when an element has an atomic number of 26?
59
What element that its atomic weight is 107.8682?
Silver (atomic number 47)
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
What is the weight atomic number for a nickel?
Nickel is a metal element. Atomic number of it is 28.
