Which phrase describes an al atom? a. a negatively charged nucleus, surrounded by negatively charged electrons b. a negatively charged nucleus, surrounded by positively charged electrons?

            None of the given options describe any atom. The phrase which describe an atom is "a positively charged nucleus surrounded by negatively charged electrons".

Explanation:
                   Atom is a smallest indivisible particle which is made up of many sub particles. The main sub particles are Protons, Neutrons and Electrons. Protons are positively charged, neutrons doesn't carry any charge hence neutral and electrons are negatively charged. Protons and neutrons are present in nucleus, therefore making the nucleus positively charged, while, electrons revolve around the nucleus in orbit hence being negatively charged particles surrounds the positively charged nucleus.

An atom is defined as the microscopic particle having positively charged nucleus around which negatively charged electrons revolve. In aluminum atom, none of the options give are correct.

Aluminum is an atom made up of 13 electrons and 13 protons. In an atom, there are several sub-particles, which are:

Protons are the positively charged sub-particle that are present inside the nucleus.Electrons are the negatively charged sub-particles that revolves around the nucleus. Neutrons does not have any charge, and is found in the nuclei of atoms.

Therefore, the correct statement is that aluminum atom have positively charged nucleus around which electrons revolve. Hence, the given options are incorrect.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
