What else can I help you with?
When disinfecting 5 gallon water can use 1 ampule of calcium hypochlorite to what ratio?
To disinfect a 5-gallon water can, use 1 ampule of calcium hypochlorite per 8 gallons of water. This will help achieve the appropriate concentration for disinfection purposes.
Why do they change swimming pool water every 8 years in California?
Water is changed when calcium hardness, cyanuric acid, or total dissolved solids become too high. In Las Vegas we recommend every two years due to high calcium hardness.
How much body calcium percent is deposited into skeleton?
206 bones800 of calcium
How many electrons does calcium have in the second energy level?
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
Is the electronic configuration of calcium 2882 or 2891?
The electronic configuration of calcium is 2882. This means that it has 20 electrons in total, with 2 electrons in the 1s orbital, 8 electrons in the 2s orbital, 8 electrons in the 2p orbital, and 2 electrons in the 3s orbital.
What is the valence electron configuration for calcium atom?
calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
What is the pH of limestone?
Limestone typically has a pH of around 8-9, making it slightly alkaline. When limestone comes into contact with water, it can raise the pH of the water due to the release of calcium carbonate.
A calcium atom bonds with another atom What is the maximum number of additional electrons the calcium atom can receive?
8
Has 8 fewer protons than calacuim?
The element with 8 fewer protons than calcium is magnesium. Calcium has 20 protons, while magnesium has 12 protons.
What is in the nucleus of the element calcium?
Calcium (Ca) contains: 20 protons (positively charged) 20 neutrons (neutral) Outside of the nucleus: 20 electrons (negative charge) with the configuration 2-8-8-2 Calcium has an atomic mass of 40.08
How many energy levels are in calcium atom?
A calcium atom has 4 energy levels. The first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, the third up to 8 electrons, and the fourth up to 2 electrons based on the electronic configuration of calcium, which is 2-8-8-2.
What is the number of of electron shells in CALCIUM?
4 electron shells; 2 electrons in first, 8 in second, 8 in third and 2 in valence shell.
