What element has 21 neutrons?
An element with 21 neutrons would have an atomic number of 11, as the number of protons in an atom determine its atomic number. Therefore, the element would be sodium (Na), which has an atomic number of 11 and typically has 12 neutrons.
How many neutrons are present in atom of iron 54?
An atom of iron with a mass number of 54 contains 30 neutrons. This can be determined by subtracting the atomic number (26) from the mass number (54), which gives the number of neutrons in the nucleus.
How many nucleon are present in phosphorus?
An average phosphorus atom has 15 protons and 16 neutrons, and it has 31 nucleons.
How many nucleons are present in phosphorous?
The average amount of neutrons in phosphorus is 16 but may vary with different isotopes
How many electrons are present in an atom of mercury 201?
121 neutrons.
How many protons are in the Hg atom?
The element mercury (Hg) has 80 protons and 80 neutrons. It exists in several different isotopes which have different numbers of neutrons, however, the average number of neutrons in a mercury atom is 121. (The atomic weight is 200.59 which would require 80 protons and 120.59 neutrons, although of course every atom has only whole numbers of neutrons, you only get fractions because you are getting an average of different isotopes.)
How many neutrons are present in radium?
Radium typically has 138 neutrons.
How many neutrons are present in the nucleus of an atom of nickel?
30 neutrons in Ni-58 isotope.
How many neutrons are present in c - 14 isotope of carbon?
The isotope 14C has 8 neutrons.
How many Neutrons are present in its Nucleus?
This depends on the individual Atom.
How many protons neutrons and electrons are present in Mg2 and O2?
45
How many neutrons are present in an atom of the isotope?
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
What is the hazardous chemical present in tube lights?
This is mercury (Hg).
How many prtons and nuetrons are in an element with an atomic number of 80?
An element with an atomic number of 80 is mercury (Hg). Mercury has 80 protons and approximately 121 neutrons in its most common isotope, mercury-201 (since 201 - 80 = 121 neutrons).
What is the maximum vacuum possible in Hg?
The maximum vacuum possible in inches of mercury (Hg) is considered to be 0 inches Hg, which represents a perfect vacuum where there is no pressure or air present.
Is Hg a homogeneous mixture or hetergeneous mixture?
Pure Hg is homogeneous. It's an element of the periodic table such as iron or oxygen ; it has 80 protons and about 120 neutrons (6 stable isotopes.
What is a real name of hg?
hg = haemoglobin , which is the oxygen carrying pigment , present in our blood Perhaps this question refers to the chemical symbol: Hg [Mercury the metal that is liquid at room temperature] Hg comes from the Latin for Mercury: Hydrargyrum.
