How many electrons are in an atom of Se?
An atom of selenium has 34 electrons.
How many covalent bonds are predicted in Se?
In its elemental form, selenium typically forms two covalent bonds. Selenium has six valence electrons in its outer shell, so it can share these electrons with other atoms to form two covalent bonds.
What is the best Lewis dot structure for element Se?
If you go to your preferred search engine and search for "lewis dot of Se" you will find it. This is the best I can make on this form....Se:.
How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
What is the symbol for selenium atoms gain two electrons?
The symbol for a selenium atom gaining two electrons is Se2-.
What atoms tend to gain two electrons to form a 2- anion?
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons
What is the correct lewis structure for selenium?
The correct Lewis structure for selenium (Se) would have 6 valence electrons represented by the symbol "Se" surrounded by 6 dots or lines (representing valence electrons), giving a total of 12 electrons in the structure.
How many electrons are in an atom of Se?
An atom of selenium has 34 electrons.
How many covalent bonds are predicted in Se?
In its elemental form, selenium typically forms two covalent bonds. Selenium has six valence electrons in its outer shell, so it can share these electrons with other atoms to form two covalent bonds.
Compare the number of valence electrons on oxygen atom has with number of valence electrons a selenium atom has Are oxygen and selenium in the same period or group?
Oxygen has 6 valence electrons, while selenium has 6 valence electrons as well. Both oxygen and selenium are in the same group, Group 16 (also known as Group VIA or Group 6) of the periodic table. They are not in the same period – oxygen is in period 2, while selenium is in period 4.
What is the valence of selenium?
Selenium is a group 16 element. It has 6 electrons in its valence shell and simply on that basis would be predicted to be divalent. and that is found to be true with compounds such as H2Se, However like sulfur it is capable of other valencies.It can be tetravalent, examples are SeO2 (which is chain polymer) and SeF4.It can also be hexavalent in SeF6, an octahedral molecular compound.And it can appear to be monovalent in for example Se2Cl2 which is actually Cl-Se-Se-Cl.
What is the best Lewis dot structure for element Se?
If you go to your preferred search engine and search for "lewis dot of Se" you will find it. This is the best I can make on this form....Se:.
What is subance?
Selenium (Se) is a solid non-metal element (#34). It has two valence electrons, meaning that it reacts similarly to sulfur and oxygen.
What is the Lewis Structure for selenium tetra hydride?
Since Selenium is in the same column as Oxygen and Sulfur, you would expect it to bond just like them. As a halogen, chlorine wants to make one bond so your final answer would be. Cl-Se-Cl with two lone pairs (that's 4 electrons) on selenium and 3 lone pairs (that's six electrons) on EACH chlorine.
What subance is selenuim?
Selenium (Se) is a solid non-metal element (#34). It has two valence electrons, meaning that it reacts similarly to sulfur and oxygen.
How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
What ion will be formed by a selenium atom when it has a stable set of valence electrons?
Selenium typically forms an ion with a charge of -2 when it gains two electrons to achieve a stable electron configuration. This forms the selenide ion (Se2-).
