Atom simulator

1. What happens when you add a proton?
When you add a proton to anempty atom,you get hydrogen. When a proton is added to an atom the atom usualy becomes stable.

2. What does it mean when an atom is stable?

3. What does it mean when an atom is unstable?
A stable atom is one that is able to hold the nucleus together, the neutrons, protons, and electrons. Unstable atoms are always radioactive. They are unable to hold all of the “parts” together, and therefore the atom becomes radioactive. Radioactive materials are made up of unstable atoms, that don’t have enough “binding energy” to hold themselves together.


4. How do you make an atom stable?

5. What do you need to do?

To make an atom stable, you need to add or take away some amount of protons, depending on the amount of neutrons that the atom has. The easiest way to stabilize an atom is to have the same amount of neutrons and protons in it, but sometimes elements like Helium, that belong with the Nobel gases, has only one neutron and two protons, the element will stay atoms will be stable.

6. What is the valence electron pattern as you move across the periodic table?


The valance electrons are, electrons that are put in the outer shell of an atom. These electrons can become a “part” of another atom, or can be share with the other atom. When valent electrons "connect" with atoms compunds are created. The valence electron pattern in the periodic table is very easy to see. When you go across a period, the number of valence electrons increases. When you start a new period,, the number of valence electrons decreases, and usually loses 1. Then, the number starts increasing again.

7. What happens to the atom when there is more protons, more neutrons, or more electrons?
The atom becomes unstable, but like in the case of helium, there are some exceptions!

8. What's the difference between a positive and a negative ion?


Ions are formed when an element, or an atom, it either loses or gains an electron. An ion becomes positively charged, when it loses an electron, because in then the number of protons gets bigger than the number of electrons. An ion is negatively charged if the opposite thing happens; an atom gains an electron. In then, there are more electrons then protons.

Current event 10 (New solar system)

There are many different solar systems, in our universe, we know this as a fact, but a new NASA telescope has detected another solar system, I will be talking about this new solar system.

NASA's “Spitzer Space Telescope” has detected signs of lots icy bodies raining in an alien solar system. The downpour is our own solar system billions years ago during a time known as the "Late Heavy Bombardment," which may have brought water and other life forming ingredients to Earth.

During this time, comets and other frosty objects that were shot out from the outer solar system smacked and damaged some of the inner planets. The hail hit our moon and due to that our moon produced large amounts of dust.

Now “theSpitzer” has spotted a band of dust around a star in the northern sky called “Eta Corvi” that has the same the materialof an obliterated giant comet. This dust is located close enough to the “Eta Corvi” that Earth like worlds could exist, which could lead to a collision t between a planet and comets. The “Eta Corvi” system is approximately one billion years old, which researchers think is about the “right age for such a hailstorm.”

Current Events 9 (MORE CO2 consumed in RAINFORESTS)

Have you ever thought to yourself; "hmmm... there’s not a lot of oxygen here" well what if I tell you that you are soooo very wrong, because science and research has shown, that in only a couple of years, trees (rainforests) will observe more carbon dioxide, therefore it is able to produce more oxygen, and we know for a fact that humans need oxygen.

North American forests appear to have a greater capacity to soak up “heat trapping” carbon dioxide gas than researchers had already thought about.

As a result, they could help slow the pace of climate warming caused by humans, most scientists had thought, a U-M ecologist and his colleagues have concluded this.

The results of a 12,year long study at an lab in “northeastern Wisconsin challenge” a lot of guesses and arguing about how future forests will respond to the rising levels of carbon dioxide “blamed for human caused climate changes,” stated University of Michigan microbial ecologist Donald Zak, lead author of a paper published online this week in Ecology Letters.

"Some of the initial assumptions about ecosystem response are not correct and will have to be revised," stated Zak, a professor at the U-M School of Natural Resources and Environment and the Department of Ecology and Evolutionary Biology in the College of Literature, Science, and the Arts.Have you ever thought to yourself; "hmmm... there’s not a lot of oxygen here" well what if I tell you that you are soooo very wrong, because science and research has shown, that in only a couple of years, trees (rainforests) will observe more carbon dioxide, therefore it is able to produce more oxygen, and we know for a fact that humans need oxygen.
