Which of the following statements are true? (There are 2) A compass needle is affected by Earth's magnetic field.

A magnetic field flows though the inside of a magnet.

Materials such as wood and plastic can become magnetized.

Electrons are responsible for generating magnetic fields.

A and B

Explanation:

the other two make no sense at all

put the answers   and i could answer.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
