Why does the nucleus have an envelop around it what are the principal roles of nucleus?
The main mass of the atom is concentrated in its nucleus which is positively charged (for having protons). For the atom to be neutral, the nucleus is surrounded by negatively charged electrons (envelop) where their total negative charge equals the total positive charge of the nucleus.
The nucleus has the following main roles:
- The nucleus has a certain number of protons that defines the element name
- The nuclei of the same element may have different number number of neutrons that define the element isotopes. Those isotopes; when radioactive; may be used for medical diagnosis, medical treatment, industry equipment, agriculture R&D, dating of some excavations, fire protection, mining research, ... etc
- some heavy nuclei (fissile material) would be used for nuclear energy generation by nuclear fission.
- light nuclei (as deuterium and tritium) could be useful for nuclear energy generation by nuclear fusion (still under R&D and not commercially available).

What information is most important to determine the size of the orbital?
The most important information to determine the size of an orbital includes the principal quantum number (n), which indicates the energy level and average distance of the electron from the nucleus. Additionally, the effective nuclear charge experienced by the electron and the type of orbital (s, p, d, f) also play critical roles in defining the shape and size of the orbital. Overall, these factors together influence the spatial distribution of electrons around the nucleus.
Why are there 3 subatomic particles?
Protons, neutrons, and electrons are the three main subatomic particles in an atom. Protons and neutrons are found in the nucleus while electrons orbit around the nucleus. They have different properties and roles in determining the characteristics of an element.
What are the major roles of the nucleus and what parts of the nucleus carry out these roles?
functions:1: One of its functions is to store the cell's hereditary material, or DNA2: The other function is it coordinates activities, including growth and reproduction (cell division).Structures:nuclear envelope with pores, nucleolus (site of ribosome production), nucleoplasm, and chromatin (genetic material)
How is the nucleus like a heart?
The nucleus is like a heart in the sense that it is essential for the cell's survival and function. The nucleus, like the heart, contains genetic material (DNA) that regulates all cellular activities, similar to how the heart regulates blood flow in the body. Both the nucleus and the heart are vital organelles that play key roles in maintaining the overall health and functioning of the cell or organism.
What are the roles of the cell nucleus?
it controls the whole cell and other parts. it can control a plant cell, animal cell, sperm cell, egg cell etc..

What is the different between a principal dancer and principal soloist in ballet company?
The Corps de Ballet is the backbone of a ballet company and performs in all the large group sections of a ballet. The female Corps de Ballet in many classical ballets must be very well rehearsed so they can maintain symmetrical lines and perform in perfect unison. A dancer who excels in the Corps de Ballet may be promoted to a Second Soloist and be asked to perform smaller group dances and some solo roles. Demonstrating their talent and strength as a Second Soloist, can lead a dancer to being promoted to First/Principal Soloist. As a Principal Soloists, dancers are given more solo roles to perform and are groomed for principal roles. When a dancer has reached a certain level of technical ability and artistic maturity, they are promoted to Principal Dancer, the highest ranking of dancer. Principal Dancers perform starring roles in a company's repertoire.

What are the Three subatomic particle roles in chemical bonding (protons electrons neutrons)?
Protons are positively charged particles found in the nucleus of an atom that determine the element's identity. Electrons are negatively charged particles that surround the nucleus and are involved in forming chemical bonds. Neutrons are neutral particles found in the nucleus that help stabilize the nucleus and do not directly participate in chemical bonding.

Where is endoplasmic reticulum located in cell?
The endoplasmic reticulum (ER) is a network of membranes found in the cytoplasm of eukaryotic cells. It can be either rough ER, which has ribosomes attached, or smooth ER, which lacks ribosomes. Rough ER is involved in protein synthesis and processing, while smooth ER plays roles in lipid metabolism and detoxification.
