Aufbau
comes from the German word “Aufbauen” which means “to build”. In essence when writing electron configurations we are building up electron orbitals
What are 10 elements examples?

What does the 6 represent above the C?
The element
carbon
(C) has an atomic number of 6, which means that all neutral carbon atoms contain 6 protons and 6 electrons. In a typical sample of carbon-containing material, 98.89% of the carbon atoms also contain 6 neutrons, so each has a mass number of 12.

What do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called
Lanthanides
. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. … The lanthanides are between Barium and Hafnium.

What are types of element?
The three types of elements are
metals, non- metals and metalloids
.
What is not example of element?
Element non examples include
all compounds
, which are substances made when two different types of atoms form a chemical bond. Any material made by mixing elements is no longer an element. Anytime you see a chemical formula with more than one element symbol in it, it’s an element non example.
What is the difference between elements and components?
There is
certainly a difference
between elements and components. Furthermore, a component refers to a small part of a larger entity that mostly is a manufactured object. In contrast, an element is one the simplest parts of which anything consists of.
