Students are completing a table about a particular subatomic particle that helps make up an atom.A 3-column table with 2 rows. The first row has entries Mass (a m u), location, charge. The second row has entries 1/2,000, nothing, has a charge.
What best explains how they should complete the table?
with “Inside the nucleus,” because the particle is a proton
with “Inside the nucleus,” because the particle is a neutron
with “Outside of the nucleus,” because the particle is a proton
with “Outside of the nucleus,” because the particle is an electron
Answers
Answer:
with “Outside of the nucleus,” because the particle is an electron
Explanation:
The table is best completed with “Outside of the nucleus,” because the particle is an electron.
The particle being described is an electron.
Electrons are negatively charged particles with a mass that is about of protons and neutrons
Mass(a.m.u) location charge
outside of the nucleus negative charge
Electrons orbits round the nucleus in distinct energy levels.
Final answer:
The subatomic particle described in the table is an electron, which is found outside of the nucleus of an atom.
Explanation:
The particle described in the table has a mass of 1/2,000 atomic mass units (a.m.u) and carries a charge. Based on this information, we can conclude that the particle being described is an electron. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom, meaning they are found outside of the nucleus. Therefore, the correct entry for the location column in the table should be Outside of the nucleus.

Final answer:
Phase changes occur at specific temperatures under standard pressure and involve either absorption or release of heat energy. This process involves the modification of kinetic energy and intermolecular forces.
Explanation:
The relationship between phase changes and temperature or heat energy is that phase changes occur at specific temperatures under standard pressure and involve either absorption or release of heat energy. This is based on the theory of kinetic energy and intermolecular forces. For instance, when ice melts to become liquid water (also known as melting), it does it at a specific temperature which is 0 degrees Celsius under 1 atm pressure. During this phase change, the ice absorbs heat energy from the surroundings without changing its temperature.
