Questions & Answers

Q: What is the difference between an ion and an atom?

An atom is electrically neutral, with an equal number of protons and electrons. An ion is a particle that has an unequal number of protons and electrons, resulting in a net positive or negative charge.

Q: How do you determine the number of protons, neutrons, and electrons in an ion?

The number of protons can be found by looking at the atomic number, while the number of neutrons is calculated by subtracting the atomic number from the mass number. The number of electrons can be found by subtracting the ion's charge from the atomic number.

Q: How do you name molecular compounds and ionic compounds?

Molecular compounds composed of nonmetals are named using prefixes like mono, di, tri, etc., to indicate the number of atoms. Ionic compounds, made up of a metal and a nonmetal, are named using the metal's name followed by the nonmetal's name with the ending "ide".

Q: What is percent composition and how do you calculate it?

Percent composition is the percentage by mass of each element in a compound. It is calculated by dividing the mass of the element by the mass of the compound, then multiplying by 100%.

Summary & Key Takeaways
