The series of levels surrounding the nucleus in an atom are referred to as electron shells. These shells represent different energy levels where electrons are located. As you move farther from the nucleus, the energy levels increase, allowing for more electrons to occupy them. The electrons in the outermost shell, known as the valence shell, play a key role in determining the chemical properties of the atom.

What does a nucleus do in protein production and modification?
The nucleus is where transcription of DNA into mRNA occurs, which is the first step in protein production. It also controls the regulation of gene expression by coordinating which genes are transcribed. After mRNA is produced, it is exported to the cytoplasm for translation into protein.
From smallest to largest What are the levels of organization in a multicellular organism?
Multicellular organisms are made in a series of levels. These levels include cells, tissues, organs, then systems which make up the organism.
Where would you find a cell's DNA in a cell?
A cell's DNA is typically found in the nucleus of the cell, organized into structures called chromosomes. Some cells, like red blood cells, may not have a nucleus, in which case the DNA is found in the cell's cytoplasm.
Where are Nucleotides used for DNA replication in eukaryotic cells made?
Nucleotides used for DNA replication in eukaryotic cells are made in the nucleus of the cell. They are synthesized from precursor molecules such as sugars, phosphate groups, and nitrogenous bases in a series of enzymatic reactions.
Which series is arranged in order from larest to smallest in size?
The correct order is: Universe, Galaxy, Solar System, Planet.
Elements across a series have same number of?
Elements across a series have the same number of attributes or characteristics.
What is a series of tubes?
nucleus
The Bohr model of the atom was able to explain the Balmer series because?
The Bohr model of the atom was able to explain the Balmer series by proposing that electrons orbit the nucleus in quantized, discrete energy levels. The transition of electrons between these levels corresponds to the emission of light at specific wavelengths, which gives rise to the spectral lines observed in the Balmer series.
What cell is a series of tubes?
nucleus
What are the characteristics of series connections?
Characteristics of parallel connection.
How are electrons organized in the area outside the nucleus?
Electrons are organized in energy levels or shells outside the nucleus. These energy levels are designated by the quantum number n. Electrons fill the lowest energy levels first before moving to higher ones, following the Aufbau principle.
What are the characteristics of the BMW 3 Series?
There are many characteristics of the BMW 3 series. The main characteristics are the design. The front of this car is different from all the other models.
Why does hydrogen emit several colors in the Balmer series?
Hydrogen emits several colors in the Balmer series because the electrons are transitioning between various energy levels within the hydrogen atom. Each color corresponds to a specific energy difference between these levels, resulting in the emission of different wavelengths of light. This phenomenon is a characteristic of the quantized energy levels of the hydrogen atom.
What is the difference between an electron and a neutron?
An electron has a mass of 1/1840 of an atomic mass unit, carries a charge of -1 and is found in one of a series of energy levels outside the nucleus of an atom. A neutron has a mass of 1 a.m.u., carries no charge and is found in the nucleus of atoms.
Which series is arranged in order from largest to smallest in size 1chromosome nucleus cell DNA nucleotide?
cell, nucleus, chromosome, DNA, nucleotide
Electrons are organized in a series of what around the nucleus of an atom?
Electron shells, orbitals, and sub-orbitals.
What series list particles in order from smallest to greatest?
Electron, proton, nucleus, atom
