List the particles that make up an atom. What are their charges? How are they arranged? What is the approxiamate amu of each particle?
I don't know
The particles that make up an atom are called protons, neutrons, and electrons. Here's how you can find the answers to your questions:
1. Protons: Protons are positively charged particles found in the nucleus of an atom. The number of protons determines the atomic number of an element.
2. Neutrons: Neutrons are neutral particles found in the nucleus of an atom. They have no charge.
3. Electrons: Electrons are negatively charged particles that orbit the nucleus of an atom in energy levels or shells. They are much smaller in size and mass compared to protons and neutrons.
To find their charges:
- Protons: The charge of a proton is +1.
- Neutrons: Neutrons have no charge, so their charge is 0.
- Electrons: The charge of an electron is -1.
To find how they are arranged:
- Protons and neutrons are located in the central nucleus of an atom, which is at the center.
- Electrons exist in specific energy levels or shells surrounding the nucleus. These shells are divided into subshells, which are further divided into orbitals.
Approximate atomic mass unit (amu) of each particle:
- Protons and neutrons: Each proton and neutron have a mass of approximately 1 amu.
- Electrons: Electrons have a much smaller mass, typically expressed as 1/1836 amu. This number accounts for their small contribution compared to protons and neutrons.
Keep in mind that these values are approximate because the mass of an electron is much smaller compared to protons and neutrons. The actual values may vary slightly based on the specific isotopes of an element.
