If an atom has 6 protons and 7 neutrons it will have 7 electrons if it is a neutral atom.

NO

Explanation:

To maintain electric neutrality, the atom has to have equal number of electrons and protons. Therefore, it needs to have 6 electrons to be neutral.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
