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....
What is the highest occupied energy level in Sn?
If you are talking about the ground state, then the quantum numbers for Tin are: n=5 l(lowercase L)=1 m-sub l = 0 m-sub s = 1/2 Learn about the relationship between electron configuration (which you know based off the placement of the element in the periodic table) and quantum numbers if you seek an explanation for this.
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).
How prepare the SnSe alloy?
To prepare SnSe alloy, you can first mix the desired ratio of tin (Sn) and selenium (Se) powders. Then, heat the mixture in a controlled environment, such as a furnace, at a specific temperature to allow the elements to react and form the alloy. Finally, cool the alloy slowly to room temperature to ensure a homogeneous structure.
How many core electrons does Sn have?
Sn (tin) has 50 electrons 50 protons and 69 nuetrons
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.
This atom in its unbound state has four valence electrons?
That would be carbon (C), silicon (Si), germanium (Ge), Tin (Sn), etc.
What atom has 38 protons 50 neutrons and 36 electrons?
The atom with 38 protons, 50 neutrons, and 36 electrons is Strontium (Sr), as the number of protons determines the element. It belongs to the alkali earth metal group and is commonly used in fireworks and flares to produce a bright red color.
Does sn gain or lose electrons?
Sulfur typically gains electrons to form a stable electron configuration. It can gain up to two electrons to achieve a full valence shell of eight electrons.
What is the Lewis Structure of SnO2?
SnO2 has total valence electron of 16e.......... since Sn is the least electronegative then it has to be in the middle of the molecular structure....O = Sn = O
An Sn atom had 50 protons and 70 neutrons in its nucleus What is its mass in AMU?
The mass of an Sn atom with 50 protons and 70 neutrons can be calculated by adding the masses of each particle. The atomic mass unit (AMU) of a proton is approximately 1.0073, and the AMU of a neutron is approximately 1.0087. Thus, the total mass of the Sn atom would be (50 * 1.0073) + (70 * 1.0087) = 118.71 AMU.
What is the Lewis Dot Diagram for Sn?
The Lewis Dot Diagram for Sn, which represents the element tin, has four valence electrons in its outer shell. This results in the symbol Sn surrounded by four dots. The Lewis Dot Diagram illustrates the arrangement of valence electrons in an atom, providing a visual representation of its bonding capabilities.
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.
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 elements are in SnF2?
There are three elements in SnF2: one tin (Sn) atom and two fluorine (F) atoms.
