b) nanoscale
c) biochemical
d) invisible

The term describes technology that operates on an atomic level is:

Explanation:

Remember that the word atomic comes from the word atom, and since an atom has an approximate size of 0.1 nanometers, regularly all technology that has similar sizes is often called nanotechnology or nano-scale technology. This technology is extremely interesting in the field of medicine, since it is expected to be able to create robots of similar sizes to an atom that can easily access and repair any organ without the need for invasive surgeries.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
