What else can I help you with?
Which element has an atomic weight?
All elements have an (atomic) weight or mass.
Which element has no atomic weight?
all elements have an atomic weight, because all of them have electrons and protons, and every electron and proton have a weight.
Is the molecular weight the same as its atomic weight?
The molecular weight is the sum of the atomic weights of all the atoms contained in the molecule.
The formula mass of neon is equal to its?
The formula mass of neon is equal to its atomic mass in atomic mass units (amu). This is because neon, like all elements, exists as individual atoms and its formula weight is the same as its atomic weight.
What is the atomic weight of the element potassium?
The atomic number of potassium is 19 and the atomic weight is 39.0983 grams per mole. See the Web Links to the left for a periodic table where you can find the atomic number and atomic weight of all the elements!
Do all atoms weight the same?
No, not all atoms weigh the same. The weight of an atom is determined by the combined mass of its protons, neutrons, and electrons. Different elements have different numbers of protons, neutrons, and electrons, leading to variations in atomic weight.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
What element has the same number of atomic shells as sodium?
All of the elements in the same period (row) of the periodic table as sodium have this property.
An average of the masses of all the naturallly occurring isotopes of an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
What is the atom weight of hydrogen?
The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of mass.
What element is the lightest of the elements?
Hydrogen is the lightest of all elements. According to the Periodic Table, its atomic weight is 1.00794 u, even lighter than helium.
How can you predict an atoms approximate weight if you know its atomic number?
The atomic number is the number of protons or electrons in an atom (there are the same amount of protons and electrons in an atom unless it's positively or negatively charged). The atomic weight is the average weight of the protons or electrons plus the neutrons of all the different isotopes of the atom. That's one of the reasons why the atomic weight of each element on the table of elements is not an integer. If you multiply the atomic number by two, you'll have a fair estimate of the atomic weight for the top part of the periodic table. For the heavier elements, this will come up a little bit light.
