This equation shows us the parent atom, which is calcium-37. The mass number is written above the atomic number for the atom. The arrow indicates the decay process with the products to the right of the arrow. The products are an atom of potassium-37 and a positron, which is similar to an electron but it carries a charge of +1 instead of a charge of -1. We can see that the transition of a proton to a neutron in positron decay decreases the atomic number of the atom from 20 to 19, but the mass number of 37 remains the same.
Step-by-step explanation:
2/10 in simplest form:
First, we can start out by finding the greatest common factor (GCF) of the numerator (2) and the denominator (10). This should always be done when simplifying a fraction the quickest way. Let's list out the factors of each number and find the common ones.
Factors of 2: 1, 2
Factors of 10: 1, 2, 5, 10
The GCF is 2, considering that 1 and 2 are the common factors, but 2 is the greatest.
Second, our last step is to divide
our numerator and denominator by the GCF (2) to find out our simplified fraction.
