How does the body act to maintain homeostasis? How do you calculate the Atomic number? How do you calculate the mass number? What products are formed when an acid and a base are mixed? How does the number of valence electrons in an atom determine its reactivity? What are the four elements found in the body? What are the four organic compounds found in the body? What is the basic structure of the cell membrane and its function? What are the stages of tissue repair?
Understand the Problem
The question is asking for clarifications on various topics related to biology and chemistry, covering concepts such as homeostasis, atomic structure, chemical reactions, cellular functions, and tissue types. It emphasizes the understanding of scientific principles and how they interact within living organisms.
Answer
Atomic number = number of protons; Mass number = protons + neutrons
To calculate the atomic number, count the number of protons in the nucleus of an atom. To find the mass number, sum the number of protons and neutrons in the nucleus.
Answer for screen readers
To calculate the atomic number, count the number of protons in the nucleus of an atom. To find the mass number, sum the number of protons and neutrons in the nucleus.
More Information
The atomic number is fundamental in determining the identity of an element, as each element has a unique number of protons.
Tips
A common mistake is confusing atomic number with mass number. Remember, atomic number relates only to protons, while mass number includes both protons and neutrons.
