Question

click the link here to open the atom-building interactive, and click the atom square. use the interactive to answer the following questions. note: keep all atoms neutral (net charge = 0) for this exercise. be sure to select the plus sign to expand the element, mass number, and net charge windows. make a he atom with a mass of 4. how many protons did you put in the nucleus? make a li atom with a mass number of 7. how many electrons did you place in the outermost orbital (ring)? make a n atom with a mass number of 14. how many neutrons are in the nucleus? make a b atom with a mass number of 11. how many electrons did you put in the second orbital (ring)? done

Explanation:

These questions are about atomic structure (protons, electrons, neutrons, mass number, neutral atoms) which falls under Chemistry (a subfield of Natural Science). To solve:

1. He atom (mass 4): Atomic number of He is 2 (protons = atomic number for neutral atom), so protons = 2.
2. Li atom (mass 7): Atomic number of Li is 3 (protons = 3, electrons = 3 for neutral). Electron configuration: 2,1. Outermost orbital (ring) has 1 electron.
3. N atom (mass 14): Atomic number of N is 7 (protons = 7). Mass number = protons + neutrons → 14 = 7 + neutrons → neutrons = 7.
4. B atom (mass 11): Atomic number of B is 5 (protons = 5, electrons = 5 for neutral). Electron configuration: 2,3. Second orbital (ring) has 3 electrons.

Answer:

1. For He atom: 2 protons.
2. For Li atom: 1 electron in outermost orbital.
3. For N atom: 7 neutrons.
4. For B atom: 3 electrons in second orbital.
