How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
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
How many protons neutrons and electrons does silicon-30 have?
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
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 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
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 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
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
How do we know what makes up the atom?
An atom contain protons, neutrons and electrons.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
How many protons neutrons and electrons does silicon-30 have?
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
How do you figure out protons electrons neutrons?
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
