What is the difference between A1 and A13+
(in simple short)
5 answers
A1 is a lower grade of standard for construction aggregates, typically used for base layers and foundations. A13+ is a higher grade, with superior quality and performance, often used for premium construction projects and high-stress applications.
whats the difference with electrons
Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. They play a crucial role in determining the chemical properties of an element and how it interacts with other elements. Electrons are involved in the formation of chemical bonds between atoms, which determine the structure and properties of molecules.
how many
The number of electrons in an atom varies depending on the element. The number of electrons in an atom is equal to the number of protons in the nucleus, as atoms are electrically neutral. The periodic table of elements provides information on the number of electrons in each element. For example, hydrogen has one electron, helium has two, oxygen has eight, and so on.
