Answer:
Mass number
Nucleus
Explanation:
The combined number of protons and neutrons is the mass number in atomic notation.
The atomic number is just the number of protons alone.
The nucleus holds both neutrons and protons.
Electrons circle around the nucleus.
Answer:
A. 11
Explanation:
atoms are made of three types of sub atomic particles - protons, neutrons and electrons
Protons are positively charged, electrons are negatively charged and neutrons are neutral.
Protons and neutrons are located inside the nucleus and electrons orbit around the nucleus in energy shells.
Atoms make up an element and atoms are neutral charged with an equal number of protons and electrons. Neutral atom of sodium would therefore have an equal number of positive charges and negative charges.
Since Na has 11 protons, for it to be neutral it would have 11 electrons
