Chem Q2&3 Flashcards
1
Q
What are three similarities between e’s and planets?
A
- both planets and e’s travel on levels
- both orbit a larger object
- both are in constant motion
2
Q
What are some differances between e’s and planets? (3)
A
- gravity holds planets around the Sun, while opposite charges hold e’s around the nucleus
- e’s can jump levels, while planets can’t
- planets travel an established orbit arounf the Sun, while e’s travel randomly on thir energy level aroubf the nucleus
3
Q
What are two properties to e’s closer to the Nuc?
A
- less energy
- more attracted to the nuc
4
Q
What are three e’s farther away from the nuc?
A
- more energy
- less attarted to nuc
- easier for e’s tp jump out of the atom
5
Q
What is a neutral atom?
A
an atom that has the same # of por & e’s, “neutral” electric charge
6
Q
Does the number of e’s ever change?
A
the # of pro stay that same for an elements but the # of electrons can change
7
Q
What do atoms what?
A
to be stabel, not nuetral
8
Q
What are the two ways an atom can become stable?
A
8 outside electrons
full outer energy level; He
9
