If an atom of tin has a mass number of 118 and an atomic number of 50 how many neutrons are in its nucleus?
AnswerProtons = 4Neutrons = 5There are four protons, four electrons, and five neutrons.You can find the number of protons by looking and the atomic number, and because this atom is not an ion (a charged atom), the number of protons and electrons are equal.You can find the number of neutrons by subtracting the number of the protons from the atomic mass. In this case, 9 minus 4 equals 5 for the number of neutrons. Your atom is the element beryllium, and is specifically the one stable isotope of that element, 9Be.
What is the electron dot diagram for lead?
"The electron dot diagram is used by scientists to represent electron sharing. The chemical symbol is in the center to represent the nucleus and inner energy level. Dots surrounding the symbol represents the valence electrons." that is the electron dot Diagram.. Sorry, i cant do more than that....
Where can tin be found on earth?
Tin is located in group 14 and in the period 5 . It's symbol is Sn. Tin, on the periodic table is under the letter's SN, it's number 50 of the element's between IN (Indium) and SB (Antimony).
If a simple machine provide sn increased output force what happens to the output distance?
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
What are the discoveries by SN Bose?
S.N. Bose made no dicovery, he actually taught and showed the world a new way of physics and mathematics S.N. Bose made no dicovery, he actually taught and showed the world a new way of physics and mathematics
What is the number of valence electrons for Sn?
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
How many core electrons in sn?
Tin has 46 core electrons.
How many core electrons does Sn have?
Sn (tin) has 50 electrons 50 protons and 69 nuetrons
Does sn gain or lose electrons?
sn lose 4 electrons
What atom has 38 protons 50 neutrons and 36 electrons?
This is an ionized atom of strontium-88 (+2 charge). Strontium is element number 38, and the most common isotope has an atomic mass of 88. In ionic compounds, it "loses" two electrons.(No neutral atom can have 38 protons and 36 electrons, as the number of protons and electrons, with opposite charges, must always be equal.)
This atom in its unbound state has four valence electrons?
That would be carbon (C), silicon (Si), germanium (Ge), Tin (Sn), etc.
How to do ionization using electron beam?
An electron beam fires electrons at an atomic structure, where the negative charge of the electron becomes electrostatically attracted to the positive charge of the protons in sn atom's nucleus. The electron begins orbiting the atomic nucleus on an energy level with other electrons, the total number of which determines the electrical charge of the resulting ion. Simply put, adding 1 electron to a neutrally charged particle (an atom) will add 1 negative charge to the overall structure. So, by firing electrons at an atom, you will only ever create positive ions.
Which atom is larger Si or Sn?
sn is larger but si is larger if your talking about ionization energy
What are the number of electrons tin has?
if you want a neutral atom of tin, you would need 50 electrons, because there are 50 protons. you can also conclude this because tin's atomic number is 50. the atomic number always equals the number of protons, and the number of protons always equals the amount of electrons.
How many atoms are in Sn3(PO4)2?
Assuming one molecule of SnO2, there are 3 atoms. 1 Tin (Sn) atom. 2 Oxygen (O) atom.
If the atom is assumed to be a sphere what is the volume of a single Sn atom?
1.15*10^-29 VERY small.
What is the symbol for tin when it lost 2 electrons?
The cation is (Sn)2+.
