Question:Hi, I am an eighth grade student. I have to do a science project making a model for the sodium atom. I really want to do well on this project, but I'm not quite sure how to do it. I do not want this to be too complicated, but I do want to make it look like used a lot of effort. Not only look, but i do want to make a decent effort. Please help me out here. Thanks!

Answers:You want to show that the atom has a nucleus with protons and neutrons has three electron layers with 2+8+1 electrons You make the nucleus of marbles or of playDoe -- one color for protons, another for neutrons. Get them hold together -- with glue, plastic film, or alike to show they are held together by sub-atomic forces. make electrons as balls of another color. Show that they belong to different layers -- e.g. by drawing the bands on the mat (you are probably want to attach every to a mat).

Question:i am doing a project on atoms and molecules. ive run into a big problem. im making a 3d model of ions and ionic bond formation. ive already made my models but now i need to show the structure and describe their functions. ive searched and searched on different sites but no luck. could someone please help me? (breakdown)- what does it mean when it says "show the structures and describe their functions"?

Answers:"Show the structure" usually refers to the arrangement of the atoms within the molecule or the crystal lattice, but "describe their functions" is very vague and not a topic usually discussed. If this project is for a class, talk with the instructor about this. Your 3D model will "show the structure." This might be very simple for a substance like Sodium chloride. The Sodium cations (positive charge) are smaller than the Chloride anions (negative charge). If "describe their functions" is a reference to what is the function of the cations and anions in the crystal lattice, then one could say that the attraction of the ions is what makes the Ionic bonds which hold the ions in place. These ionic bonds are broken when the salt is dissolved in water.

Question:The project im doing is Sodium from the periodic table. My 2 questions are. *What are the correct number of shells? *What are the correct number of electrons in each shell?

Answers:there are three shells and there is one electron on its outer shell, two electrons on its first shell, and 8 electrons on its second shell

Question:please show the 5 models of atom

Answers:Go to this web site and you will see the image of the 5 models of atoms. 1) The first model was called the chocolate pudding model. An Atom was solid as chocolate pudding and as uniform. 2) They then discovered there were electrons in atoms. So they call this the pudding model with raisins. Think of it as a pudding model with raisins stuck to it. 3)The Rutherford model was the previous model with a nucleus added. 4) The next model was simply electrons orbiting a nucleus like planets orbiting the sun. 5) The last model was the nucleus with only a high probability of where you will find electrons.
