Electron orbitals are essentially 3-dimensional maps showing the probability of finding an electron within a region in an energy level.
To understand probability mapping, lets think about our Principal, Mr. Waters. Lets pretend that we have attached to him a device which reports to us his position on campus every five minutes for an entire school week. We [...]
Warm up for the benchmark on balancing nuclear equations! You will need a periodic table to complete this activity.
As a warmup for today’s benchmark, complete the following table. You are encouraged to use a periodic table.
1. If an atom has a mass # of 209 and has 127 neutrons in its nucleus, what is the name of this element?
2. If another atom has 92 protons and has a mass # of 240, what is the name of the atom and how many neutrons does it have in its nucleus?
