Atoms share electrons to create chemical bonds. Understanding the nature of this bonding begins Understanding the nature of this bonding begins by knowing the number of electrons associated In our examples, only SO 4 2- is a charged ion; it has the negative charge 2. Add this value to the total...So to get the number of electrons, you must subtract the size of charge (which is often written as a superscript on the right side of the symbol) from the atomic number or proton As you can see, Mg has an atomic number of 12 and a charge of +2, so to get the number of electrons for Mg ion, we...Mass number: total number of protons and neutrons in the nucleus (not listed on the periodic table, since it Mass number - atomic number = # neutrons. Determining the number of electrons If the charge is positive, subtract that number from the atomic number to get the number of electrons.An ion (/ˈaɪɒn, -ən/) is a particle, atom or molecule with a net electrical charge. The charge of the electron is considered negative by convention. The negative charge of an ion is equal and opposite to charged proton(s) considered positive by convention.107 electrons and a +1 charge equals 108 protons. The density of an unknown liquid was calculated to be 0.78 g/ml. If the accepted value is 0.75 g/ml, calculate the percent error made.?
How to calculate the number of electrons in an ion
An ion is nothing more than an electrically charged atom. Adding or removing electrons from an For example, removing an electron from an atom of krypton forms a krypton ion, which is usually written as Kr+. Happily, to find the mass number, all you need to do is round the atomic weight to the nearest...Answer to What is the mass number of an ion with 107 electrons and 159 neutrons and a + 1 charge Question: What Is The Mass Number Of An Ion With 107 Electrons And 159 Neutrons And A + 1 Charge.The number on the upper left corner is the mass number, which is equal to the neutrons and protons added together. Lastly, the charge is on the upper right corner. If there isn't any number or signs, then it means that atom has no Rules to Finding Number of Protons, Neutrons, and Electrons.An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (the atomic number) from the mass number to find the...
Determining Protons Neutrons and Electrons of Atoms and Ions
In this case 159+107=266. However, since this ion has a +1 charge, you must add 1 to the electrons. This would give a total mass of 267. When a chlorate decomposes what is produced? none of these O Oxygen gas O Water Carbon dioxide Sulfur trioxide.A = mass number = Number of protons in nucleus + Number of neutrons in nucleus Number of protons = Number of electrons + 1 ( since the charge is +1 due to lacking one electron ) Number of protons = 105 + 1 = 106 protons A = 106 protons + 159 neutrons = 265.Of neutrons=158. Help with Questions in Chemistry. How many SO32 - ions are contained in 99.6 mg of Na2SO3? The molar mass of Na2SO3 is 126.05 g/mol.A = 262 An atom's mass number will tell you how many protons and neutrons can be found in said atom's nucleus. color(blue)("mass number" = "no. of protons" + "no. of Instead, it tells you that you're dealing with an ion that has a +1 charge and a total number of 104 electrons surrounding its nucleus.What is the mass number of an ion with 104 electrons, 159 neutrons, and a +1 charge? Given what you know about the human body, what do you think accounts for the high percentage of oxygen (65.0%)? - The human body breathes in oxygen constantly, and oxygen in the blood and tissues...
How is this a biology question? It appears like chemistry.
Anyway, if the ion has a +1 charge, then the number of electrons are going to be one not up to the number of protons.
Therefore, the number of protons in the nucleus will have to be 108.
And the mass number is simply the sum of protons and neutrons, so add 159 + 108 in combination, and you get a mass number of 267.
