What is different between secondary electron image and back scattered electron image?
Secondary electron images show morphology and topographyof a sample. The more the number of electrons reaching the detector, the brighter the image is. Back scattered electron images show difference in composition - or more exactly, difference in atomic number over a sample. The higher the atomic numbers of the atom, the more backscattered electrons are bounced back, making the image brighter for larger atoms.
A second difference is back scattered electrons are produced by the elastic interaction of the beam electron with nuclei of atoms in the specimen. No energy is lost as it is elastic interaction. On the other hand secondary electrons are produced by inelastic interaction of beam electrons with electrons in the atom rather than the nucleus. Since it is inelastic interaction, there is energy loss.

What kind of bond results when electron transfer occurs between atoms of 2 different elements?
The kind of bond that results when electron transfer occurs between atoms of two different elements can be considered covalent, polar covalent, or ionic. The type of bond will depend upon the identities of the elements and their electronegativity's.
The force between the nucleus and the outermost electron for the large atom is?
The force between the nucleus and the outermost electron in a large atom is primarily governed by the attraction between the positively charged nucleus and the negatively charged electron. This force is known as the electrostatic force of attraction and is directly proportional to the product of the charges and inversely proportional to the square of the distance between the nucleus and the electron.
Is an example of an electrostatic force acting in an atom neutron attracting an electron a proton attracting an electron an electron attracting another electron a neutron attracting a proton?
Yes, an example of an electrostatic force acting in an atom is a proton attracting an electron. This attraction occurs due to the opposite charges of the proton (positive) and the electron (negative), leading to the electrostatic force of attraction between them.
Does N and Br have a covalent bond?
Yes, nitrogen (N) and bromine (Br) can form a covalent bond when they share electrons to achieve a stable electron configuration. Covalent bonds involve the sharing of electron pairs between atoms and can occur between different nonmetals like N and Br.
The fewer electron shells the shielding of electrons from the nucleus.?
less
What is the different between absolute and secondary instrumentation?
secondary instruments are calibrated.absolute instruments are not calibrated. secondary instruments are used everywhere,ab instru are only in labs or std institutions.
How are primary and secondary waves alike How are they different?
the petrographical interaction between them are at different levels therefore occurring in different wave lengths.
What is the different between primary absorbance and secondary absorbance in fluorescence?
in primary light absorbed by outer molecule while in secondary re-absorbance occurs
What is the different between primary and secondary lesions?
primary lesion is a macule, papule, pustlie, vesicle secondary lesion is a ulcer, crust, scar, skin atrophy, excoriation
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Hydrogen bonds between different parts of the polypeptide chain contribute to the secondary structure of proteins, specifically in the formation of alpha helices and beta sheets. These secondary structures then further fold and interact to form the tertiary structure of the protein.
What are 4 causes of scatter radiation?
Compton scatter: Interaction between an incoming X-ray photon and an outer-shell electron results in the photon changing direction. Photoelectric effect: Absorption of X-ray photon by inner-shell electron leading to emission of a secondary photon. Pair production: High-energy X-ray photon interacts with atomic nucleus, creating an electron-positron pair. Rayleigh scatter: Low-energy X-ray photon interacts with an atom without ionization, resulting in a scattered photon with the same energy.
Similarities between primary and secondary research?

The difference between primary and secondary reserves?
what are the diffrence between primary reserve and secondary reserve?
Why do spacecraft not melt in the heat of the million degree corona of the sun?
The matter in the corona is scattered really thin so it doesn't pass much energy to the objects in it. Think about it as the difference between being hit by an extremely light electron travelling at 10km/s and car at 100km/h. You won't even notice the electron.
What provides a bridge between primary and secondary groups?
Reference groups, which are groups that individuals compare themselves to and use as a standard for attitudes, behaviors, and identity, can provide a bridge between primary and secondary groups by influencing how individuals interact with different social groups and navigate their relationships between them.
Why is secondary called secondary?
Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.
What is the difference between primary ans secondary industry?
secondary is cooler
