Plant cell walls are rigid membranes on the outermost part of the cell. The cell wall provides a structured shape for the cell, helping the cell retain its form and shape. The cell wall also controls the rate of replication, allowing plant cells to replicate at a much slower rate than animal cells.

Answer:
In the n=1 energy level, the atom has 2 electrons
Explanation:
Electrons orbit the nucleus of an atom in multiple rings (energy levels). The first ring of the electron can only hold 2 electrons. After that, electrons are added to the second ring. Excluding the first ring, all other rings can hold a maximum of 8 electrons.
For example, Oxygen is an atom with 6 electrons. The first energy level contains 2 electrons, and the second energy level contains 4 electrons. The second energy level has room for up to 4 more electrons.
In your example of an atom with 15 electrons, there would be 2 electrons in the first ring, 8 electrons in the second ring, and 5 electrons in the third and final ring.
To summarize, all atoms have a first energy level containing 2 electrons, and all other energy levels can contain 8 electrons. This is true no matter the number of electrons.
