The term "valence electrons" refers to all of the electrons in an atom's outermost shell.
The centre of the atom is where the nucleus is. The nucleus contains protons and neutrons. The electrons travel in a specific circular direction and at a specific distance from the nucleus.
The atom's final shell's electrons take part in chemical reactions and the production of bonds. Both ionic and covalent bonding involve valence electrons. Metals are elements with one, two, or three electrons in their final shell.
These substances become positive ions after losing their electrons. Non-metals are substances with 5, 6, or 7 electrons in the outermost shell. These substances all gain electrons and change into negative ions.
Ionic bonds are those created by the transfer of electrons between metals and non-metals. For instance, ionic bonding allows sodium and chlorine to interact to generate sodium chloride.

Steps 1 and 3 are correct rate
<span>Magnetic domain
Its speed can be slowed because the magnetic field can be turned on and off, can have its direction reversed and can have its strength changed. However, The speed of a magnetic field that is produced by a current is impossible to be slowed. </span>
Answer:
Pseudoscience
Explanation:
Predicting the future based solely on the position of the planets is an example of <u>pseudoscience</u>.
<em>Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.</em>
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.
