Question

3 what particle(s) are found in the center of the atom? 4 play until you discover. which particle(s) determine(s) the name of the element you build? 5 what is the name of the following atoms? a an atom with 3 protons and 4 neutrons. b an atom with 2 protons and 4 neutrons. c an atom with 4 protons and 4 neutrons. 6 play with the simulation. which particles affect the charge of an atom or ion? 7 fill in the blanks below to show your results: a neutral atoms have the same number of protons and electrons. b positive ions have protons than electrons. c negative ions have protons than electrons.

Explanation:

These questions relate to atomic structure, a key topic in chemistry. Answers are based on fundamental atomic properties: nucleus composition, atomic number (protons) defining elements, charge determined by proton-electron balance.
