How are 15 electrons arranged in a phosphorus atom?
When we write the configuration we’ll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom. In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital.
Which element has the greatest number of protons?
uranium
Where is Moscovium found?
Moscow Oblast
What is the symbol for an ion which has 17 protons and 18 electrons?
The ion that has 17 protons and 18 electrons is a chlorine ion. This is the sulfide ion, S2-. See the answer.
Which two nuclei have the same number of neutrons?
Nuclei with the same number of neutrons (N) but different atomic numbers are termed isotones 19 40 K and 18 40 Ar are examples of isobars, while 1 3 H and 2 4 He are examples of isotones.
How do you find the number of neutrons in chlorine?
Each proton and neutron has a relative mass of 1 unit. Therefore we can subtract the number of protons from the atomic mass number in order to work out the number of neutrons. Chlorine has a mass number of 35, minus the 17 protons means that chlorine has 18 neutrons.
What is the mass number for chlorine?
35.453 u
What are the 3 uses of chlorine?
Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.
What is the symbol of chlorine and why?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature.
Is chlorine acidic or basic?
When chlorine (in any form) is added to water, a weak acid called Hypochlorous acid is produced. It is this acid, not the chlorine, which gives water its ability to oxidize and disinfect. Proper chlorination and filtration give pool water its clear, sparkling appearance. Chlorine exists as a solid, a liquid and a gas.
What is the chemical name for chlorine?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.
