Last thursday, august 30, 2007... We discussed more about nucleus... Here are some of the definitions: Gravitational - always attractive; determined by mass. Electrical - maybe repulsive or attractive; determined by charge. _*weak and strong*_ - nuclear forces; attractive. Atomic # - same as # of protons; charge Mass # - sum of protons + neutrons.
We also learned more about alpha, beta, gamma, positron and negatron..
And as usual, we had a quiz.. My score is a lil' bit lower than my previous quiz... But it's fine. I'll improve. ^^,
