Question 2: how do we know about electrons if they're so tiny
Science often talks about things we can't see, feel, or hear. So how do we know they exist? Well the National Science Teachers Association says, imagine your in a dark room where you can't see anything. Your chained to a chair and all you have is a pile of rocks. Technically you don't know your in a room with a door, windows, and blah blah blah. But if you throw a rock in all directions you can hear if something is there(wall). You could also tell how far away the thing is by how long it takes the rock to hit the thing. Also a rock might make a different sound if it hits a door. And even though you still can't be sure walls and a door are there, the sounds could have been made by something else, your pretty sure from the data you collected your in an enclosed room. So just like the room scientists are pretty sure electrons exist because of the data they collected.
Question 5: what will the model of the atom look like in the future
Scientists at CERN and at Fermilab have been hoping to find a particle or set of particles called a Higgs boson They say the Higgs boson might give others mass. Scientists are trying to figure out if a Higgs boson exists by smashing particles together at high speeds. If the energy from the collision is high enough it is made into more particles, one of which could be a Higgs boson. But the Higgs boson would only occur fora few seconds then it would decay into something else so the scientists are looking for something it would have decayed into. If scientists eventually find out if the Higgs boson exists it would be put on a new model of the atom.
