gain 2 electrons
The central atom in selenium sulfide has a bent molecular geometry due to the presence of two lone pairs on the selenium atom. This results in a distorted tetrahedral arrangement around the selenium atom.
This atom must gain 3 electrons to achieve an octet.
There are 34 protons in a selenium-76 atom.
Selenium has the largest atom among phosphorus, sulfur, and selenium because of its larger atomic radius. This is due to selenium having more electron shells and thus a greater distance from the nucleus.
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
An atom of selenium will gain two electrons to achieve an octet because it has six valence electrons in its outer shell. By gaining these two electrons, selenium will have a total of eight electrons in its outer shell, fulfilling the octet rule.
Yes, SeO2F2 and ONF3 contain atoms with expanded octets. In SeO2F2, the selenium atom has 12 electrons around it, exceeding the octet. In ONF3, the nitrogen atom has 10 electrons around it, also exceeding the octet. However, GaCl3 does not have any atoms with expanded octets as gallium follows the octet rule.
The octet rule cannot be satisfied in molecules whose total number of valence electrons is an odd number.There are also molecules in which an atom has fewer, or more, than an octet of valence electrons.
Sulfur hexachloride is an inorganic compound consisting of two different elements. The prefix hexa indicates that there are six chloride atoms. Thus, the formula is SCl6. Note that this compound does not obey the octet rule.
The central atom in selenium sulfide has a bent molecular geometry due to the presence of two lone pairs on the selenium atom. This results in a distorted tetrahedral arrangement around the selenium atom.
Sulfur must to have an electrons octet.
This atom must gain 3 electrons to achieve an octet.
A potassium atom has 1 electron in its outer shell. In order to satisfy the octet rule, it needs to donate 7 electrons to another atom to reach a stable configuration with a full outer shell.
There are 34 protons in a selenium-76 atom.
Selenium has the largest atom among phosphorus, sulfur, and selenium because of its larger atomic radius. This is due to selenium having more electron shells and thus a greater distance from the nucleus.
