How do you find the 11th electron configuration?
To write the electronic configuration, we need to know (i) the atomic number (ii) the order in which orbitals are to be filled (iii) a maximum number of electrons in a shell, sub-shell or orbital. (b) The number of electrons to be accommodated in a subshell is 2 number of degenerate orbitals.

What is electronic configuration of elements?
The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. The valence electrons, electrons in the outermost shell, are the determining factor for the unique chemistry of the element.
What is the electronic configuration of an element with an atomic number of 11?
Electronic Configuration of First 30 Elements with Atomic Numbers

| 11 | Sodium (Na) | [Ne] 3s1 |
| 12 | Magnesium (Mg) | [Ne] 3s2 |

What is the smallest unit of an element?
An atom is the smallest unit of a pure substance or element that can exist and still retain the properties of the original substance or element.
What’s the difference between elements and compounds?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What are 2 differences between elements and compounds?
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Elements that compose the compound are chemically combined. Elements contain only one type of atom.
Can be broken down into two or more components?
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. mixtures are phisically combined structures that can be seperated into their original components. A chemical substance is composed of one type of atom or molecule.
Which is considered a mixture?
A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components. Some examples of mixtures are a tossed salad, salt water and a mixed bag of M&M’s candy.
Can compounds be broken down?
Compounds can be broken down into smaller compounds, or their basic elements, by chemical change. Heat can also be used to break down sodium hydroxide into the simpler compounds sodium oxide and water. Electrolysis is a chemical change produced by sending an electric current through a compound.
Is smoke a mixture?
Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion, so we can say that smoke is the mixture.
Is soda a homogeneous mixture?
For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture.
What is the composition of smoke?
Although smoke can contain hundreds of different chemicals and fumes, visible smoke is mostly carbon (soot), tar, oils and ash. Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely). In complete combustion, everything is burned, producing just water and carbon dioxide.
