13 billion years ago and Hydrogen
1 of 9
Why are elements with even atomic numbers more abundant?
The are more stable
2 of 9
What are the two types of neutron capture used to create elements after iron?
S-Process, An external neutron is added to create an unstable isotope that undergoes beta decay to form a new element . R-process, Happens at a much faster rate. When nucleus is full every neutron the enters knocks another out.

How do you build a solar system? (Card 1)
1. A large amount of cosmic dust that starts to slowly rotate and contract 2. Rotates faster as in collapses in on itself increase particle collision that due to conservation of energy cause the dust to heat up.

How do you build a solar system? (Card 2)
3. Dust concentration develops in the middle and rings form around this. 4. Fusion starts in the dust concentration (protostar) and then eventually a star. 5. The rings of dust clump together to form plants

What are the characteristics of inner planets?
High density, Mostly metal, rock and water, Hydrogen and oxygen can fuse to form water

What are the characteristics of outer planets?
Low density, gas giants, Mostly methane and ice.
