Can someone describe major subatomic particles that make up an atom

Biology

irinina [24]3 years ago

The main 3 subatomic particles that makes up an atom are protons, neutrons, and electrons.

Protons and neutrons exists inside the nucleus of the atom, while electrons moves freely outside the nucleus.

Protons are positive in charge, each element has their own specific number of protons, it's just like their ID number for the element, they cannot be changed.

Neutrons are neutral, just like as it name says. Usually they have the same number as the protons in most elements, but not all cases. Sometimes an element may even have a few different forms, called Isotopes specifically, where they have different number of protons for each isotope.

And electrons, are negative in charge. They're a lot more lighter comparing to neutrons and protons, therefore sometimes we neglect their mass in calculating maths. In an atom, the number of electrons must be the same as the number of protons, or else, the atom would no longer be an atom, but an ion instead.

which type of transport would be required for the solute molecules to move against the concetration gradient?
larisa [96]

Answer:

<u><em>Active Transport</em></u>

Explanation:

<u><em>active transport </em></u>

During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
