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.
Which group will have an electron configuration that ends in s2?
Elements in Group 2 of the periodic table will have an electron configuration that ends in s2. This group includes elements such as beryllium, magnesium, and calcium. They have two electrons in their outermost s sublevel.
What is the the electron configuration of N?
1s2 2s2 2p3 (the numbers at the end of each little thingymabober are smalll like exponents!)
If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
Aluminum or sulfur configuration ends in 3p1?
Two aluminum atoms and three sulfur atoms are combined in the compound aluminum sulfide (2 Al + 3 S = Al2S3).
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 does the electron configuration for sulfur end?
The electron configuration for sulfur end with 3p4.
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.
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 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 are the group numbers and the generic outer electron configurations for a neutral atom?
Group numbers are used in the periodic table to indicate the number of valence electrons in an element. The generic outer electron configuration for a neutral atom can be determined by looking at the group number: Group 1 elements have 1 valence electron and end in s1, group 2 elements have 2 valence electrons and end in s2, group 13 elements end in s2p1, etc.
What is the electron configuration for Heluim?
Helium is at the end of row 1 in the periodic table 1s2
WhAt is the ending of the electron configuration of each element in group 4?
Elements in Group 4 end their electron configurations with 4s2 4p2. This is because they have 4 valence electrons, with the last two electrons occupying the s-subshell (4s) and the p-subshell (4p) completing the outermost energy level.

What are the electron configurations of the first two elements in group 17?
F = #9, 9 electrons 1s2, 2s2, 2p5 Cl = #17 , 17 electrons 1s2, 2s2, 2p6, 3s2, 3p5 Notice both end in s2, p5. That is why they have similar properties. Both only need 1 electron to complete the octet ( s2 p6 in the outer shell, very stable)
Is 1s2 2s2 2p6 3s2 3p6 4s2 4d10 4p5 valid?
Bromine
