How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
What did daltons theory say about protons and electrons?
Nothing,Dolton did not know about Protons,neutrons and electrons
How may electrons neutrons protons are foundin the helium atom?
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
Did Mendeleev know about protons neutrons and electrons?
No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.
How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
How many protons electrons and neutrons does Au- 197 have?
Au-197 has 79 protons, 79 electrons, and 118 neutrons. The atomic number of gold (Au) is 79, indicating the number of protons. The isotope Au-197 specifies the atomic mass, which is the sum of protons and neutrons. So, subtracting the atomic number from the atomic mass gives the number of neutrons.
How many neutrons are in iridium?
Indium have:protons = 49neutrons = 66electrons = 49to know how to get the protons, electrons and neutrons:protons = atomic number of the elementelectrons = protons or atomic number of the elementneutrons = mass number-atomic number
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
An atom composed of 16 protons 16 electrons and 16 neutrons is?
This is an atom of sulfur, which we know by the number of protons. And it's a neutral atom of sulfur, because the number of electrons equals the number of protons. Also, we know it's the most abundant isotope of sulfur because of the 16 neutrons. A link can be found below.electrons
How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?
Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
How many electrons and neutrons does a carbon have?
6 protons 6 neutrons 6 electrons. If you can use Wikianswers then you should know how to use Google
