You would need to have to phosphate atoms and three berylium. P P P (with their respective dots- so each with 5) and then B B (with two dots) Then you can make arros pointing from the phosphorus to each Berylium atom.
Any element can have 4 neutrons but most of them aren't metallic. Anyway's on the periodic table it would be Be and that stands for Beryllium
Electronic configuration of beryllium: 1s2.2s2.
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
The symbol for beryllium is Be, and the symbol for chloride is Cl. Therefore, the symbol for beryllium chloride would be BeCl2.
After 10740 years, half of the sample would have decayed, so there would be 200 atoms left. If the original sample had 400 atoms, then there would be 200 atoms left in the sample after 10740 years.
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.
After 3 half-lives, half of the original sample would remain unchanged. After the 1st half-life: 300 unchanged atoms. After the 2nd half-life: 150 unchanged atoms. After the 3rd half-life: 75 unchanged atoms would remain.
You would need to have to phosphate atoms and three berylium. P P P (with their respective dots- so each with 5) and then B B (with two dots) Then you can make arros pointing from the phosphorus to each Berylium atom.
When hydrogen, lithium, and beryllium atoms combine, they form a molecule with the chemical formula LiHBe. This molecule would have a unique set of properties based on the different characteristics of each element.
To determine the number of grams in a sample of 3.01 x 10^23 atoms of tellurium, you would first convert the number of atoms into moles using Avogadro's number. Then, you would find the molar mass of tellurium and use it to convert moles into grams.
Any element can have 4 neutrons but most of them aren't metallic. Anyway's on the periodic table it would be Be and that stands for Beryllium
Electronic configuration of beryllium: 1s2.2s2.
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
In each nitric acid molecule (HNO3), there is one oxygen atom. So, in a sample containing 50 HNO3 molecules, there would be 50 oxygen atoms.
The natural abundance of carbon-13 is around 1.1%. Therefore, in a sample of 13,000 carbon atoms, there would be approximately 143 carbon-13 atoms on average.
