I'm gonna make the nucleus red so we can see that a little bit better and then we can go ahead and fill in our electrons. Um so because our team is in the third round, it's gonna have three shells. In our our last shell is not going to necessarily have all eight electrons, it might be partially filled. Now we're going to stop wherever we get to our element. And then the 3rd row can hold up to eight. The second shell holds eight, Which would be the second row. So first show would be the first row of the periodic table with hydrogen and helium and that holds two electrons. So then we want to know how many shells each atom has or this atom has. So when we filmed them in into our model, we shouldn't have any more in the 12 electrons. So protons have positive charge, which means we have 12 positive charges And electrons have negative charge, which means we need 12 negatives to balance out the 12 positives. And so because elements in their natural state have no charge, the number of positive charges, the number of negative charges must be equal. Next, we want to see how many electrons the atom must have. So step four, we want to draw in our nucleus, we'll make it a little bit bigger And we'll say we have 12 protons And 12 Neutrons to indicate that. We get that from the um atomic number and then the mass number minus the atomic number gives us the number of neutrons. So we chose magnesium and find the atomic number and the mass number. Um So first we're going to look at our atoms. This is often called the Bohr model as well if you've heard of that. So, planetary model is going to be where we have the nucleus in the middle with rings surrounding it. So because there's no example provided, let's just use magnesium as our example.

Today, we're looking at drawing the atomic structure of atoms following a series of steps. Make large dots on each circle to represent the number of Draw circles around the nucleus to represent theĩ. (Note that the transition elements can hold up to 18Įlectrons in their third shell, but we will not be dealing withĨ. Second shell can hold up to 8 electrons, and, for the main groupĮlements used in this activity, the third shell can hold up to 8Įlectrons. We will assume that the first shell can hold up to 2 electrons, the Determine the number of shells of the atom. Determine the number of electrons of the atom.ħ. Inside this circle, write the number of protons and theĦ.

Next, draw a small circle to represent the nucleus (to matchĥ. To determine the number of protons and neutrons of theĤ. First, use the atomic number and mass number of the element Use the planetary model discussed in class.ģ.
