Question

practice: atomic calculations
part 1: atomic structure

1. drag 4 protons to the appropriate place on the atom to the right.
2. drag 5 neutrons to the appropriate place on the atom to the right.
3. drag 4 electrons to the appropriate place on the atom to the right. place two in the first energy level, and two on the second.
4. pick the appropriate charge from the list below and label the element with that charge.
5. what element did you just draw?
6. how do you know?

part 2: periodic table
label each part of the element on the right.

Explanation:

1. Charge is calculated as protons minus electrons: $4 - 4 = 0$.
2. The number of protons (4) equals the atomic number, which corresponds to Beryllium.
3. The atomic number (number of protons) identifies the element.

Part 2: The periodic table square labels are atomic number (7), chemical symbol (N), element name (Nitrogen), and atomic mass (14.01).

Answer:

1. 0
2. Beryllium
3. The number of protons (atomic number) is 4, which matches Beryllium's atomic number.

Part 2: Top label: Atomic Number (7); Middle left label: Chemical Symbol (N); Middle right label: Element Name (Nitrogen); Bottom label: Atomic Mass (14.01)
