In a ferrous metal, iron, if the molecules align then magnetism is formed. To show this, if you take a nail that is not magnetic and then hammer it, the molecules start to line up and it becomes magnetized.
The matter that has strong magnetism - called ferromagnetism - has the ability to form magnetic domains. That means that the individual atoms, which individually have a small amount of magnetism, tend to align themselves within small regions (the magnetic domains). If an external magnetic field is applied, the domains themselves align to the magnetic field.
Some elements are magnetic due to their nature and the properties that they posses. The dipole moment is the main determinant to magnetism of an element.
Their electrons are polarized (lacking or have too many). And so when they meet an opposite they move towards it in an attempt to balance out the charge.
Really oversimplifying it, some elements attract electrons because they don't have enough electrons to fill all their quantum energy levels.
include the halogens are nonmetals
during a chemical reaction valence electrons are most always transferred
oxygen is able to attract 2 electrons

Non-metals, especially group 17 and group 16 elements.
Nonmetals tend to attract electrons to become negative ions.

The number of loosely held electrons determines the reactivity of an element. Other elements attract electrons and will react also.
include the halogens are nonmetals
Protons do attract electrons due to the electromagnetic force.
Barium because this is have a greatest tendency.
There is no Group 14. The elements of the group 7A are the most electronegative. Basically, electronegativity is the ability to attract electrons. Group 7A elements, or halogens, need just one more electron to reach stability, and are very reactive. So, they can easily accept that electron. In other words, their ability to attract electrons is the highest.
They have a higher electronegativity than metals. Electronegativity is the tendency of an atom or a functional group to attract electrons to itself.
Elements in the same group have the same number of valence electrons.
By abstracting electrons from or donating electrons to some other chemical substance.
