Hey people i'm back and i'll be talking to you about chemical reactions. Did you know that chemical reactions happen around us all the time. A chemical reaction is even happening right now while you're reading this. Anyways, lets get back to what I was saying. The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus also contains a mix of positively charged protons and electrically neutral neutrons.
The nucleus is what is in the center of an atom. Shells are what electrons are on that surround the nucleus. Clouds are what happens when electrons spin around really fast. Now i'll be telling you about how many electrons can each shell hold. The first shell that is closest to the nucleus can hold two electrons. The second shell can hold eight, then the third can hold sixteen, then the fourth can hold thirty-two. Valence electrons are the electrons that are on the outermost shell.
Now i'll tell you the difference between when an atom is unstable and when an atom is stable. An atom that has a full shell is called stable. An atom the doesn't have a full shell is called unstable.
That's all for today people see you next week.
you had some grammer mistakes i liked your pics and i give you a B+
ReplyDeleteyour whole blog was awsome! A+
ReplyDeleteI like that you had brief informations but all containing what you need, but the last picture is kinda not related what we learned..
ReplyDeleteA+
Good job! You kept it brief, but I still understood. A+
ReplyDeleteYour info was great except the electron shells is 2,8,8,16,16,32,32... and the last pic wasnt relevant, but everything else was solid! 92%
ReplyDeleteThat was great A+
ReplyDeletegood pics and nice background, but a bit short. Overall great.
ReplyDeleteits a bit short. the pictures are nice, but i would keep the font white adn not read. it boggles the eyes. B+
