I'll solve this worksheet on atoms by filling in the blanks based on my knowledge of atomic structure.
Looking at the image, I can see it's a worksheet about atoms with several fill-in-the-blank questions:
1. Electrons have a charge of ___
2. Protons have a charge of ___
3. Neutrons have a charge of ___
4. The nucleus is made up of ___
5. Atoms have the same number of protons and ___
6. The lithium atom example has: ___ electrons, ___ protons, ___ neutrons
Let me fill these in:
1. Electrons have a charge of
negative (or -1)
2. Protons have a charge of
positive (or +1)
3. Neutrons have a charge of
neutral (or 0)
4. The nucleus is made up of
protons and neutrons
5. Atoms have the same number of protons and
electrons (in a neutral atom)
6. For the lithium atom example: Lithium has atomic number 3, so it has
3 electrons,
3 protons, and typically
4 neutrons (since its most common isotope, lithium-7, has mass number 7, so 7-3=4 neutrons)
The solution is complete. The worksheet teaches the basic structure of atoms, including the charges of subatomic particles and how they relate to each other in a neutral atom.
