What are the steps needed to draw a modified Bohr model of an atom for a specific element like Carbon? Check all that are correct.
1. Find the symbol for the element on the Periodic Table of Elements.
2. Look for the number listed above or to the upper right or left of the Atomic Symbol for the element. This is the number of protons it has.
3. Draw a circle to represent the nucleus of the atom and write the number of protons in that circle. This is important because each element is defined by the number of protons it has.
4. Draw circles around the nucleus and fill each energy shell starting with the innermost shell with the right number of electrons until the total number matches the number of protons. Remember: the innermost shell number 1 can hold only 2 electrons; the second shell can hold a total of 8; the third can hold 18 before it is filled.
5. Throw a set of dice to determine how many protons an atom of an element has.
Which is the most basic element whose atoms each have only one proton and one electron, but no neutrons? It is the source of energy for stars like the Sun and it is part of the water molecule.
Hydrogen
Carbon
Nitrogen
Helium
