It is not something you calculate. The number of protons in an atom can be determined by looking up its atomic number on the Periodic Table. In the case of silicon, the atomic number is 14, so it has 14 protons.
What else can I help you with?
How do you calculate percent abundance for silicon?
You calculate the total amount of whatever it is that you want to find the silicon abundance for. Then you calculate the amount f silicon in that. Then percentage abundance of silicon = 100*amount of silicon/total amount Typically the amount would be measured as the mass.
How many grams of silicon would there be in a sample that contained 9.99 x 1052 atoms?
To calculate the mass of silicon in the sample, you would first convert the number of atoms to moles using Avogadro's number. Then, you would calculate the mass of silicon in grams using the molar mass of silicon (28.0855 g/mol). The final mass would depend on the number of atoms in the sample.
When atoms have fewer or more neutrons than protns they are called?
Isotopes.
What is the relationship between the number of protns and the number of elecrons in an atom?
They are the same.
1 a how many silicon atoms in each unit cell b.how many silicon atoms are there in one cubic centimeter.?
a. There are 8 silicon atoms in each unit cell of a silicon crystal in a diamond cubic structure. b. The density of silicon is 2.33 g/cm^3, and the molar mass of silicon is approximately 28.09 g/mol. By using Avogadro's number, you can calculate that there are approximately 5 x 10^22 silicon atoms in one cubic centimeter.
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
What has different atomic masses?
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
How many protns neutrons and electrons does osmium have?
Osmium atoms have 76 electrons and protons, and between 108 and 116 neutrons. The isotopes with more neutrons are more abundant.
Silicon has how many neutrons?
Silicon has 14 neutrons.
How many atoms make up 3.29 g of silicon?
To determine the number of silicon atoms in 3.29 g, you first need to calculate the number of moles of silicon using its molar mass (28.0855 g/mol). Then, use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
How many grams of chlorine are required to combine with 24.4grams of silicon to form silicon tetrachloride?
To find the amount of chlorine needed to combine with silicon to form silicon tetrachloride, first calculate the molar masses of silicon and chlorine (28.09 g/mol and 35.45 g/mol, respectively). As silicon tetrachloride has a 1:4 ratio of silicon to chlorine, this means 1 mole of silicon (28.09 g) will react with 4 moles of chlorine (4 * 35.45 g) to form silicon tetrachloride. Therefore, to find the grams of chlorine needed to combine with 24.4 grams of silicon, calculate (24.4 g Si / 28.09 g Si) * (4 moles Cl * 35.45 g Cl).
How many ATOMS of silicon are present in 6.54 grams of silicon dioxide?
First let's calculate the formula mass of SiO2. It is 28.1 + 2(16.0) = 60.1. The amount of SiO2 can be calculated as 6.54/60.1 = 0.109mol. Now in one formula unit of SiO2 there is one Si atom. So, the amount of Si atoms present is 0.109mol. To get the numerical quantity, multiply it by the Avogadro's constant, and we get 0.109 × 6.02 × 10^23 = 6.55 x 10^22 atoms
