Answer:
Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.
An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)
A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.
A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.
The subatomic particle that is negative is the 'electron'.

Answer:
Trochanter
Explanation:
All of these choices are colletively known as bone markings.
Trochanter is an example of a site for a muscle or ligament attachment. We have two trochanters, the greater trochanter and the lesser trochanter. You can find these in the femur, or the thighbone. These are points where the muscle of the hips and the muscle of the thighs are attached.
Eliminating the rest:
Sinus is a cavity or a sac of air, common in the cranium (skull).
Fossa is a depression on the bone.
Foramen is an openning in the bone. You can see this in the vertebral column. There's a space or hollow area in the vertebrae where the spine runs through.
Groove is a furrow or a line that runs along the bone. It is gives space for a blood vessel to fit in so it won't get compressed by the muscles around it.
