Using the mass of the proton 1.0073amu and assuming its diameter is 1.010-15 m calculate the density of a proton in gcm3?
3.2 x 10^15 g/cm^3
What is the difference between hydrogen and deuterium lamp for UV?
Hydrogen and deuterium lamps for UV vary in the gases that are utilized in the discharge.. Deuterium lamps also generate a higher intensity radiation compared to hydrogen lamps.
How many electrons does it take to equal to the mass of one proton?
electrons are a 2000th of the mass of a proton/neutron. Because of this very low mass, electrons dont affect the mass number of elements on the periodic table
What is the positively charge atomic particle of an atom called?
A Proton
Where is the proton found in atom?
where is proton in atom
If the volume of a proton is similar to the volume of an electron how will the densities of these two particles compare?
Proton mass = approx. 1,850 x electron mass.If volumes are similar, then proton density = approx. 1,850 x electron density.
Does the proton affect the mass of an atom?
Yes, significantly so. One proton is approximately one atomic mass unit.
Using the mass of the proton 1.0073amu and assuming its diameter is 1.010-15 m calculate the density of a proton in gcm3?
3.2 x 10^15 g/cm^3
Why would one need a proton therapy?
Proton therapy is generally used as a radiation treatment for cancer patients. This differs from traditional radiation therapy in that the ray of the protons can be directed more easily and causes less damage to surrounding tissues.
What element has the lowes density of all elements?
Hydrogen because It has just 1 electron in 1 shell, orbiting 1 proton.
Is a proton is a proton is a proton. True or False?
If a proton, is a proton then it is a proton. (True).
What is the difference between hydrogen and deuterium lamp for UV?
Hydrogen and deuterium lamps for UV vary in the gases that are utilized in the discharge.. Deuterium lamps also generate a higher intensity radiation compared to hydrogen lamps.
What atomic nucleus has the highest charge density on earth?
Hydrogen - it consists of a single (charged) proton with no (neutral) neutrons. Source: Degree in Natural Sciences
How many electrons does it take to equal to the mass of one proton?
electrons are a 2000th of the mass of a proton/neutron. Because of this very low mass, electrons dont affect the mass number of elements on the periodic table
When does water act as a base and an acid?
molecules in water that release hydrogen ions (H+) are acids, while molecules in water that release hydroxide (OH-) are bases. In water solutions, acids affect water molecules, producing hydronium (H3O+) and bases also affect water molecules, producing hydroxide (OH-) ions.
Dose the proton have an impact on the size of the atom?
The proton CHARGE has an impact (if the proton's charge were different, the atom's size would be different). However, the proton SIZE is more or less irrelevant. The increase in size of the atom due to the proton is very very negligible. It has been proven that the density of the Nucleus is constant in all atoms of all elements. This means, the nucleus does increase in size, if there are more protons. However, The majority of the size of an atom comes from the electron orbits. Thus the main factor for atom size is electron orbits.
What causes a metal heavy?
Not all metals are heavy. The heavy ones have more density due to proton and neutron count. Titanium vs gold for instance.
