What Means SPDF?
The spdf stands for sharp, principal, diffuse, and fundamental respectively. These letters are used as the visual impression to describe the fine structure of the spectral lines that occurs due to the spin orbital interaction.
What is 1s and 2s in chemistry?
1s will be filled first, with the maximum of 2 electrons. • 2s will be filled next, with the maximum of 2 electrons. • 2p will be filled next, with the maximum of 6 electrons.

What type of element is carbon give some information about it?
Carbon (from Latin: carbo “coal”) is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table.
What element is Xe 6s2 4f14 5d9?
The expected electron configuration for gold is is [Xe] 6s2 4f14 5d9 but it has been determined to be [Xe] 6s1 4f14 5d10.
What are the 4 types of sublevels?
The levels can be broken down into sublevels. We have s, p, d, and f sublevels. Level one has one sublevel – an s. Level 2 has 2 sublevels – s and p.
What are the 4 quantum numbers?
In atoms, there are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).
What do NL ml and MS mean?
The first three (n, l, ml) specify the particular orbital of interest, and the fourth (ms) specifies how many electrons can occupy that orbital. 1.
What is 3S quality?
5S stands for Sort, Straighten, Sweep, Standardize, and Sustain. 3S is just three of these: Sort, Sweep, and Standardize.
What is meant by 5S in English?
Quality Glossary Definition: Five S’s (5S) 5S is defined as a methodology that results in a workplace that is clean, uncluttered, safe, and well organized to help reduce waste and optimize productivity. It’s designed to help build a quality work environment, both physically and mentally.
What is the shape of f orbitals?
There is no discrete shape in the f-subshell. This is because of the complexity of its nature. Therefore the answer would be option D, No definite shape. Note: Although we generally study uptil the f-subshell but that doesn’t mean that it is the last subshell.
What comes after 6s in electron configuration?
The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
Does F come before D in electron configuration?
The f block has the lower level filled, then for valance electrons has 2 s electrons 1 d electron and then up to 14 f electrons filling the 7 f orbitals.
How do 2px and 2py orbital differ?
The orbitals have the same size (energy) and shape, but are oriented differently in space (different magnetic quantum numbers). The 2px orbital lies on the x-axis while the 2py orbital lies along the y-axis.
Which is the correct electron configuration for Fe atomic number 26 in the ground state?
Iron atoms have 26 electrons and the shell structure is 2.8. 14.2. The ground state electron configuration of ground state gaseous neutral iron is [Ar]. 3d6.
What is 1s2 2s2 2p6 3s2 3p6 4s2 3d3?
Also, if you look at the last number/letter combination, you can go directly to that spot on the periodic table to determine the element. Example: 1s2 2s2 2p6 3s2 3p6 4s2 3d3 (This has a total of 23 electrons which equals the atomic number of V – Vanadium.)
Why carbon is an important element?
The Chemical Basis for Life. Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
Which element is in group 9 period 4?
Cobalt. Cobalt (Co) is an element in group 9. Cobalt is commonly used in pigments, as many compounds of cobalt are blue in color.
What is carbon Valency?
Hint: Valency of carbon can be defined as combining power with hydrogen. The number of valence electrons in the outermost shell in carbon is 4. To attain noble gas configuration carbon makes 4 bonds with carbon. Therefore, Carbon is tetravalent.
