2(11) + 16 + 4(8) = 70
First you would calculate the number of protons... the number of protons = the total mass number then the number of protons should = the nummber of electrons(unless their is a number in front of the element like +1) therefore= # of protons = # of electrons
The number of electrons in an atom is equal to its atomic number, which is the number of protons in its nucleus. This is because atoms are electrically neutral, so they have an equal number of protons and electrons. You can find the atomic number of an element on the periodic table.
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). Neutrons do not carry a charge and help stabilize the nucleus of an atom.
No, the mass number of an element represents the total number of protons and neutrons in its nucleus. To find the number of protons, you would look at the element's atomic number, which is the smaller number on the element's symbol.
To find the number of protons, you need to subtract the number of neutrons from the mass number. In this case, the atom has a mass number of 19 and 10 neutrons, which means the number of protons is 19 - 10 = 9 protons.
To find the volume of 0.24M Na2SO4 oxidized by 0.32 kmno4, first calculate the number of moles of KMnO4 using the formula M1V1 = M2V2. Then, use the mole ratio between KMnO4 and Na2SO4 (from the balanced equation) to find the moles of Na2SO4 oxidized. Finally, convert the moles of Na2SO4 to volume using its molarity.
To determine the number of formula units in 0.0482 mol of sodium sulfate, you first need to find the molar mass of sodium sulfate (Na2SO4). The molar mass of Na2SO4 is approximately 142.04 g/mol. Then, divide the given amount of moles by the molar mass to find the number of formula units. In this case, there are approximately 3.39 x 10^22 formula units in 0.0482 mol of sodium sulfate.
The number of protons is the atomic number.
The number of protons is equal to the number of electrons and the atomic number.
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
First you would calculate the number of protons... the number of protons = the total mass number then the number of protons should = the nummber of electrons(unless their is a number in front of the element like +1) therefore= # of protons = # of electrons
The mass number of an element like calcium is the sum of the number of protons and neutrons in its nucleus. Calcium has 20 protons, so to find the mass number, you would look up the number of neutrons in the periodic table and add that to 20.
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
# protons = atomic number.
The number of protons in the atomic nucleus is equal to atomic number.
The number of protons in an elements nucleus is the same number at the atomic number.
