can you not @oobleck :/
Come on Oobleck, I know you are even better than that. Even though it has been almost a year since you posted the comment, but still...
So no one has the answers?
The correct answer for the atomic number of an atom is D. the number of protons.
To find the atomic number of an atom, you need to count the number of protons in the nucleus. The atomic number represents the unique identity of an element, as each element has a specific number of protons in its atoms. Therefore, the atomic number determines the element's position on the periodic table.
For the statement about an atom, the correct answer is B. The electron has a negative charge and is found outside the nucleus. Electrons are negatively charged subatomic particles that orbit the nucleus in specific energy levels or shells.
To find the number of neutrons in an atom, you can use the following formula:
Number of neutrons = Mass number - Atomic number
The mass number represents the total number of protons and neutrons in the nucleus. By subtracting the atomic number (number of protons) from the mass number, you can determine the number of neutrons for the model of an atom.
Therefore, the correct answer for finding the number of neutrons in a model of an atom is A. Subtract the atomic number from the mass number.
Finally, the correct answer for the reiteration of the atomic number of an atom is D. the number of protons.
