What are the names and mass numbers and electron number and proton number and symblos of all the elements in Chemistry?
Check the Periodic Table of Elements for more information.
What is the average of the mass numbers of an elements isotopes?
the Atomic Mass
Why the mass numbers on the periodic table of elements are rarely whole numbers?
Elements also possess isotopes. So their average atomic mass is rarely whole number.
How are atomic numbers and mass numbers of elements arranged in the periodic table?
by ectron protons and neutrons
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
How do you find mass Numbers of an element?
Mass number is the number underneath the elements letter on the Periodic Table.
Name two elements have the same mass numbers?
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
What was mendeleev able to do with the properties and mass numbers?
He arranged the elements in the increasing order of atomic mass and repeating periodic properties.
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons
How are isotopes and elements different?
They have different numbers of neutrons, which changes the atomic mass and nuclear properties.
Which element has an atomic mass of11?
Atomic mass numbers are not properties of elements overall, but only of particular isotopes of elements. The only stable element with an isotope with mass number 11 is boron. Beryllium and carbon also have isotopes with mass number 11, but these are radioactive.
What data about elements are found on the Periodic Table?
On standard ones, Their Symbols, atomic & mass numbers, and groups.
