Which group will have an electron configuration that ends in s2?
The alkaline earth elements electron structure end in s2
Explain what a noble-gas electron configuration is?
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.
What is the valence electron configuration of all the noble gases?
Except for helium, whose valence configuration is 1s2, the valence configuration for the rest of the noble gases consists of the highest energy level s2p6 configuration, for a total of 8 valence electrons. The highest energy level corresponds to the row number on the periodic table. So, radon, at the end of row six, has a valence configuration of 6s26p6.
What is the the electron configuration of N?
1s2 2s2 2p3 (the numbers at the end of each little thingymabober are smalll like exponents!)
What the electron configuration for Sr2?
[Kr] 5s2
How does the electron configuration for sulfur end?
The electron configuration for sulfur end with 3p4.
What element has the electron configuration 4s2 3d7?
First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.
How would the electron configurations for sulfur end?
The atomic number for sulfur is 16. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p4. This can be shortened to [Ne] 3s2 3p4, which shows you that 3s2 3p4 is how sulfur's electron configuration ends.
What element has 2 shells and 3 valence electrons?
First of, Valence electron ground state is the number at the end of a Electron configuration in period 2 which goes across (from left to right) you see that each element has 2 numbers on the electron configuration ex Li 2-1 Be 2-2 B 2-3 C 2-4 notice that the ground state (which is the last number is in the secoond shell (I THINK)
Which elements have electron configuration that end in ns2 np5?
halogens
What is electron configeration?
Have same electronic configuration. Example Sodium ion & Neon atom have isoelectronic configuration 2,8 Have same electronic configuration. Example Sodium ion & Neon atom have isoelectronic configuration 2,8
What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
What element has the electron configuration of 1s2 2s2 2p6 3s2 3p5?
That element is chlorine (Cl). You can tell for two reasons: first, the second number in each section (which, when properly written, is a superscript) should all add up to the element's atomic number. Another reason is that the configuration ends in 3p5, which tells you that the element is in period 3, and it's one spot back from the noble gas, which automatically will end in 3p6. The noble gas is argon (Ar), so the element in question must be chlorine.
Which group will have an electron configuration that ends in s2?
The alkaline earth elements electron structure end in s2
What column contains elements whose electron configuration end with d4?
what column of the periodic table contains elements whose electron configurations end with d4
What is the electron configuration for Heluim?
Helium is at the end of row 1 in the periodic table 1s2
