[tex]\rm{\huge{ANSWER:}}[/tex]

1. The overall charge of an atom is [tex]\bold{\red{0}}[/tex].

[tex]\boxed{\sf\green{✓}}[/tex] Atoms are electrically neutral because they contain the same number of positive charges (protons) as they do negative charges (electrons).

2. The positive particles in an atom are called [tex]\bold{\red{protons}}[/tex], and the negative particles are called [tex]\bold{\red{electrons}}[/tex].

[tex]\boxed{\sf\green{✓}}[/tex] Neutrons, which have no charge, are also present in the nucleus of an atom.

3. [tex]\bold{\red{No}}[/tex], not all atoms of all elements are the same.

[tex]\boxed{\sf\green{✓}}[/tex] Each element has a unique number of protons in its nucleus, which determines its atomic number and chemical properties.

[tex]\boxed{\sf\green{✓}}[/tex] For example, a carbon atom has 6 protons, while a nitrogen atom has 7 protons.
