What are the lines outside of the nucleus called?
The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surrounds the nucleus, which encases the genetic material. The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane.
What are the lines around the nucleus?
A bluish purple line around the edge of the nucleus is the nuclear envelope/nuclear membrane. The small darkly staining granules are chromatin (chromosomes). The larger dark purple structure is the nucleolus.
What is on the outside of a nucleus?
Around the outside of the nucleus is an envelope consisting of two layers of membrane. Scattered over the outer surface of this nuclear envelope is a series of circular openings known as nuclear pores, and between the two membranes is a small space.
What do rings around the nucleus represent?
The circles in the nucleus of the atom represent positively charged neutrons and neutral neutrons. The smaller circles outside the nucleus represent negatively charged electrons. The electrons are held in orbit around the nucleus because opposite charges attract.
What does the line between the electron and nucleus represent?
The lines in the spectrum of an element represent changes in the energy of electrons within the atoms of that element. The energy of an electron depends on its location with respect to the nucleus of an atom. The higher the energy of an electron in an atom, the farther is its most probable location from the nucleus.
What does the line represent in an atom?
When atoms are excited they emit light of certain wavelengths which correspond to different colors. The emitted light can be observed as a series of colored lines with dark spaces in between; this series of colored lines is called a line or atomic spectra. Each element produces a unique set of spectral lines.
How do electrons move around the nucleus?
The electron travels in circular orbits around the nucleus. Energy is emitted from the atom when the electron jumps from one orbit to another closer to the nucleus.
In which direction do electrons move around the nucleus?
Electrons have properties that are analogous to classical spin and orbital angular momentum. But, they don’t really spin or orbit. Here is the simple answer it is counterclockwise.
Do electrons orbit the nucleus?
Unlike planets orbiting the Sun, electrons cannot be at any arbitrary distance from the nucleus; they can exist only in certain specific locations called allowed orbits. The electron travels in circular orbits around the nucleus. The orbits have quantized sizes and energies.
What does each line represent in the emission and absorption spectra of an incandescent gas?
Each line in the emission and absorption spectra of an incandescent gas represents the energy released or absorbed as it travels between the orbital levels.
What do the lines in a line spectrum represent?
What do the individual lines in a bright line emission spectrum represent? They represent the wavelengths of light that is absorbed by the spectrum They represent the energy that the atom gives off when their electrons are in place.
What holds the electrons in orbit around the nucleus?
Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Are electrons inside or outside the nucleus?
Electrons are outside the nucleus in energy levels. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. A neutral atom contains equal numbers of protons and electrons. Why are the electrons outside the nucleus but not inside the nucleus?
What is inside the nucleus of an atom?
The nucleus is surrounded by electrons sloshing around, but these electrons are not particles that whizz about. Once you get to atomic length scales, quantum mechanics starts to kick in and you need to start describing things as having wave-like character.
What is the difference between nucleus and cloud of electrons?
The nucleus of an atom contains the protons and neutrons in the atom. Surrounding the nucleus is a cloud of electrons, much larger than the nucleus but containing only a tiny fraction of the atom’s mass.
What do absorption lines tell us about a star’s interior?
The absorption lines produced by these outermost layers of the star tell us a lot about the chemical compositition, temperature, and other features of the star. Absorption lines are based on the same physical principle as emission lines: they involve an atom jumping from one particular energy level to another.
