The notation Rn 7s² 25f¹ 26d¹ describes an element in the Periodic Table. It indicates that the element has a filled 6p subshell (Radon, Rn) plus additional electrons in the 7s, 25f, and 26d orbitals. This corresponds to the element Copernicium (Cn), which has the atomic number 112. Copernicium is a synthetic element with very limited availability and is highly unstable.

What element out of K K plus Rb Rn plus has the smallest radius?
The element with the smallest atomic radius among K (potassium), Rb (rubidium), and Rn (radon) is Rn (radon). As you move down a group in the periodic table, atomic radii increase due to the addition of electron shells. However, radon is a noble gas with a completely filled outer shell, which leads to a relatively smaller effective radius compared to the alkali metals K and Rb. Therefore, Rn has the smallest radius among the given elements.
The polynomial given roots?
Do mean find the polynomial given its roots ? If so the answer is (x -r1)(x-r2)...(x-rn) where r1,r2,.. rn is the given list roots.
What is the rule for the sum of the first n terms of a geometric series?
Suppose the nth term is = arn where n = 1,2,3, ... Then the sum to the nth term is a*(rn+1 - 1)/(r - 1) or, equivalently, a*(1 - rn+1)/(1 - r)
What is the total mass of rn 222 remaining in an original 160 mg sample of rn 222 after 19.1 days?
To determine the remaining mass of Rn-222 after 19.1 days, we need to use its half-life, which is approximately 3.8 days. After 19.1 days, which is about 5 half-lives (19.1 days / 3.8 days), the remaining mass can be calculated using the formula: remaining mass = initial mass × (1/2)^(number of half-lives). Thus, the remaining mass of Rn-222 is 160 mg × (1/2)^5, which equals approximately 5 mg.
Can an rn with a as make a six figure salary?
Yes. RN's can make as close as 100k a year. Think about the little overtime they do and alternate weekends, a Nurse usually paid $47 an hour comes close to $67 an hour and that is not even counting everyday work.
What is the noble gas configuration of francium?
The noble gas configuration of francium is [Rn]7s^1, where [Rn] represents the electron configuration of radon, a noble gas element. Francium has one valence electron in the 7s orbital, making it highly reactive.
What is the noble gas notation for einsteinium?
The electron configuration of einsteinium is [Rn]5f11.7s2.
What is the noble gas configuration for element 117?
The noble gas configuration for element 117 (Tennessine) is [Rn] 5f^14 6d^10 7s^2 7p^5. This means it has the same electron configuration as Radon up to its 5f electron level, followed by the filling of the 6d and 7s orbitals, and finally with 7p orbitals.
What is the electron configuration of element hassium?
The electron configuration of hassium is: [Rn]5f14.6d6.7s2.
What is the noble gas notation for berkillium?
The noble gas notation for berkillium (Bk) is [Rn] 5f^9 7s^2. This notation indicates that berkillium has the same electron configuration as radon (Rn) for its inner electrons, followed by 5f^9 7s^2 for its valence electrons.
What is the noble gas notation of Ra?
The noble gas notation for radium (Ra) is [Rn] 7s². This notation indicates that radium has the same electron configuration as radon (Rn), which is the nearest noble gas, followed by two additional electrons in the 7s subshell.

What is the correct electron configuration for Md?
The correct electron configuration for mendelevium (Md), which has an atomic number of 101, is [Rn] 5f^13 7s^2. This indicates that it has 13 electrons in the 5f subshell and 2 electrons in the 7s subshell, following the radon (Rn) noble gas core.
What would be the electron configuration for element 118?
This would be a rather large electron configuration with somehwere around 27 valence electrons.... its kind of like playing with fire stating these facts though since this elements has been discovered but not fully confirmed.
What is electron configuration of Hs?
The electron configuration for hassium (Hs) is [Rn]5f146d67s2.
