Question

can this group help me with my chemistry??

Answer 1

There is a chemistry Study Group; at the main menu, look at the bottom and click on the link for "view all groups". There is likely going to be more specific help there.

Answer 2

I can help! What do you need?

Answer 3

Analyze the properties of a sodium atom and a sodium ion. What are the differences in mass, stability, and reactivity that are caused due to the differences between the sodium atom and sodium ion?

Answer 4

Sodium has an atomic number 11. That means it has 11 protons in its nucleus. A neutral atom of sodium will have 11 electrons around it. An ion will have an unequal number of protons and electrons in it. Sodium is very reactive, and we don't find it free in nature. It is always found in combination with another or other elements in compounds. When you put salt in water, it "comes apart" into sodium and chlorine ions in the water. Sodium metal, for example, which consists of neutral sodium atoms, bursts into flame when it comes in contact with water. Positively charged Na+ ion combined with a negatively charged chlorine ion together are nonreactive, so we can ingest them safely as table salt. Mass is calculated by the sum of the mass of protons, electrons, and neutrons. However the mass of an electron is not really included. So when a sodium atom looses or gains an electron, the mass is unchanged. I hope this helped! Please ask if you have anymore questions :)

This is the website I used to help me with my chemistry homework-
