Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
Consider the following data for the element Z.
what is a) percent of abudance and average mass (in g/mol) of this element?
| Isotope 1 | Isotope 2 | Isotope3 | |
| Mass (amu) | 22.56 | 30.4 | 39.00 |
| % of Abundance | 10.50 | 50.45 | a. |
| # of protons | 16 | 16 | |
| # of electrons | 16 | ||
| # of neutrons | 23 |
Every atom in periodic table has some atomic mass and atomic number. When atomic number of two elements is same and atomic mass is different, they are called isotopes.
The total sum of abundance of all isotopes of an element is 100 %. Weighted average of is calculated by using atomic mass of its isotopes and their relative abundance.
Here percentage abundance of two isotopes is given; calculate for third isotope as total percentage abundance is 100.
