How do you make an atom model? PLEASE HELP ANY IDEAS GUYS?

Answers

Answer:

If you are looking for like a drawing say less.

If you are physically making one you would need to 1. Glue balls together to represent protons and neutrons. This is the nucleus. Try to arrange them in an alternating pattern. 2. Glue the nucleus to the center of the cardboard. 3. Determine how many rings you need for the electrons. Starting from the innermost ring, you can have up to two electrons in the first ring, up to eight in the second ring, up to 18 in the third ring and up to 32 in the fourth ring. 4. Glue the string around the nucleus to make the energy level rings. 5. Apply a few drops of glue to each ring. 6. Glue the electrons on the rings, spacing them evenly. Make sure you don’t exceed each rings maximum number of electrons. If you are trying to draw one then you could easily find one online

Answer:

Interphase: the cells spends most of its time here. DNA is duplicated prior to cell division

Prophase: The cell prepares for division, DNA condenses into chromosomes

Metapahse: chromosomes line up in the middle of the cell

Anaphase: the chromosome copies pull apart and away to the far sides of the cell

Telophase:  the cell forms new membranes for each of the 2 nuclei and tears in 2 during cytokinesis
