Problem
Given the following information about atoms, determine the name of each atom's element and its atomic number.
a. Atom 1 has 11 protons
b. Atom 2 has 20 electrons
1. Analyze the Problem
Apply the relationship among atomic number, number of protons, and number of electrons to determine the name and atomic number of each element.
2. Solve for the Unknown
a. Atom 1
Atomic number = number of protons = number of electrons
Atomic number = ______ = number of electrons
An element with an atomic number of 11 is ______.
b. Atom 2
Atomic number = number of protons = number of electrons
Atomic number = number of protons = ______
An element with an atomic number of ______ is ______.
3. Evaluate the Answer
The answers agree with the periodic table.
