What else can I help you with?
How do you know how many unpaired electrons are in an element?
You can determine the number of unpaired electrons in an element by examining its electron configuration. Unpaired electrons are found in the outermost energy level, and you can count them by looking for half-filled or singly occupied orbitals in the notation of the element.
What Atom has 2 completely filled shells and no electrons anywhere else?
The atom that has 2 completely filled electron shells and no electrons anywhere else is helium. Helium has a total of 2 electrons, with both shells being completely filled with 2 electrons in the first shell.
What is the neutral atom that has its first two energy levels filled has 6 electrons in its third energy level and has no other electrons?
The neutral atom with the specified electron configuration has 10 electrons in total. This atom is neon (symbol: Ne), which has a total of 10 electrons and has its first two energy levels filled with 2 and 8 electrons, respectively, while the third energy level contains 6 electrons.
How would the electrons produced in a cathode ray tube filled with neon gas compare with the electrons produced in a cathode ray tube filled with chlorine gas?
JJ Thompson passed an electric current through a gas at low pressure from the negative terminal to the positive terminal then decided that the ration is always the same regardless the gas used.
The exosphere Is filled with electrically charged ions?
The exosphere is the outermost layer of Earth's atmosphere where the density is extremely low. It is composed of a mix of gases such as hydrogen, helium, and oxygen. While there may be some ions present in the exosphere, it is not considered to be "filled" with electrically charged ions.
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
How many electrons does it need to have in the outermost energy level filled?
8 electrons
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
How many electrons does carbon need to have the outermost energy shell filled?
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
What are the electrons in the outermost energy level of an atom are called?
Completely filled octet.
What are the set of 8 electrons in an atom's outermost energy level called?
Completely filled octet.
What element out of lithium neon silicon helium and chlorine have a filled outermost shell?
Neon has a filled outermost shell, as it belongs to the noble gas group and contains a full set of valence electrons.
How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
If the outermost electron shell of an element is not filled with electrons to its maxium capacity the element is not chemically active?
false
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
An atom with an incompletely filled outermost energy level is likely to be?
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.
