How do you find the number of bacteria?
To know the number of bacteria is impossible but approximate to approximate number can be calculated by using electron microscope. To find the exact number is impossible because bacteria keeps on dividing every 5-10 minutes.
How do you calculated electrons?
electron equals the atomic number
How many microscope are there?
There are six different types of microscopes used in the life science. There is the light microscope, phase contrast microscope, fluorescent microscope, electron microscope, atomic force microscope, and scanning tunnelling microscope.
Why are such a limited number of organelles observed when viewing the plant and animal cells under the microscope?
Most organelles are very small and require a magnification greater than the x1500 available using a light microscope. An electron microscope is required for greater magnification and resolution. Therefore a small area of the slide is avalible.
How is a simple microscope and a compound microscope different?
The difference lies in the number of lenses that each microscope has. A compound microscope has 2 or more lenses, like those found in most science classrooms. A simple microscope uses only 1 lens.
Are electrons equal to newtrons?
No, number of electron is not equal to the number of neutron ,as we can predict it from the difference of their masses only,
Why is mass number calculated with only the protons and neutrons and not electrons?
Because the mass of electron is negligible when compared to the mass of protons or neutrons.
How do you determine electron density given atomic density?
The electron density is simply deduced from the atomic density as follows : if ne denotes the electron density and na the atomic density then : ne= z na with z being the number of valence electron per atom.
Is the universe an electron?
An electron is very small. So small that you cant even see it with an electron microscope (because it uses electron to detect itself). It's mass is tiny. Billions of times less than a kg. It's just one type of matter. Some estimates put the number of electrons in the universes at greater than 10100. So no, the universe is not an electron.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What is a compound microscope used for in lab equipment?
A compound microscope, like the common optical microscope is used to study objects too small to see with the naked eye. The difference between a common optical microscope, and a compound microscope is the number of objective lenses. A compound microscope will contain several lenses. This reduces distortion, and gives one multiple lenses with which to adjust magnification.
What are the atomic numbers for silver and gold?
Gold: Symbol - Au Number - 79 Mass - 196.96655 (As calculated by all of its known ions) Electron Configuration - [Xe] 6s2 5d9 Charge - 1+, 3+ Silver: Symbol - Ag Number - 47 Mass - 107.8682 (As calculated by all of its known ions) Electron Configuration - [Kr] 5s2 4d9 Charge - 1+
