True or False? Assume that we take only the magnitude of charge when calculating specific charge unless told otherwise

True

What does “Specific” mean?

Per unit mass

How does Carbon Dating work?

Living organisms contain a constant ratio of C-12 : C-14

When organism dies, it stops taking in Carbon, and C-14 begins to decay

By find the ratio of C-12:C-14 we can work out the number of half lives, thus the age of the organism

How do you calculate Relative Atomic Mass given the relative abundance of isotopes?

Avg.mass = [(m₁ %₁) + (m₂ * %₂)] / [100]

How do you find the average specific charge of a sample of ions or isotopes?

Find the individual specific charges

Use the relative abundances to find the average

What is the quark combination for a positive, neutral, and negative Kaon?

positive : up anti-strange

neutral : down anti-strange

negative : ant-up strange

Which energy level does E₁ refer to in : hf = E₁ - E₂ ?

The higher energy level

Subtracting a more negative number will give a positive number
