What is electronic structure of matter?
Electronic structure is the state of motion of electrons in an electrostatic field created by stationary nuclei. The term encompass both the wavefunctions of the electrons and the energies associated with them. Atomic Orbitals. This page discusses atomic orbitals at an introductory level.
What is an atom in chemistry PPT?
• Atoms are the smallest particles of matter.

| Z | Element | Group |
|---|---|---|
| 1 | Hydrogen | 1 |
| 2 | Helium | 18 |
| 3 | Lithium | 1 |
| 4 | Beryllium | 2 |
What is the electronic structure rule?
This rule describes the order in which electrons are filled in all the orbitals belonging to a subshell. It states that every orbital in a given subshell is singly occupied by electrons before a second electron is filled in an orbital.
What is the electronic structure of the first 20 elements?
Given below is a table describing the electronic configuration of first 30 elements with atomic numbers….Electronic Configuration of First 30 Elements with Atomic Numbers.
| Atomic Number | Name of the Element | Electronic Configuration |
|---|---|---|
| 18 | Argon (Ar) | [Ne] 3s2 3p6 |
| 19 | Potassium (K) | [Ar] 4s1 |
| 20 | Calcium (Ca) | [Ar] 4s2 |

How do you draw electronic structure?
How to draw an electron configuration diagram
- Find the element on the periodic table.
- Draw a small circle and write the symbol in the centre.
- Draw a circle around the nucleus.
- Add up to two electrons to the first electron shell.
- Draw another circle around the first shell.
- Add up to eight electrons to the second shell.
What are the 3 parts that make up all atoms?
We now know that atoms are made up of three particles known as subatomic particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.
Is electronic structure the same as electronic configuration?
electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.
What is the electronic configuration of 2 7?
(a) The atomic number of the atom is 9 (electronic configuration 2, 7) since it is the sum total of the electrons present in an atom (2+7=9). (b) The atom would be chemically similar to 17Cl as its electronic configuration is 2,8,7.
