What is the full electron configuration that's in group 2 in the fourth period?
The inert gas in Period 2 is the element Neon(Ne). Its electron configuration is 2-8.
Have two valence electrons and get to a stable electron configuration by using two electrons?
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
What is calcium-42 electron configuration?
The element calcium, or Ca, is located in group 2, period 4 of the periodic table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
What element has the electron configuration of Kr 5s2 4d10 5p3?
Group 1- as the configuration is ns1. The Kr in the question indicates the Krypton core. The 5s1 is the clue - the period number is the same as the principal quantum number (in this case 5) so the element is in group 1 and period 5 - so it is rubidium.
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
What can the period of a element be determined by?
electron configuration
An element that has the electron configuration Ne3s23p5 is in which period?
It is in group 17.
What period and group does an element with electron configuration 6s2 6p6 belong to?
Radon!
What is the electron configuration for an element in group 2,period 3?
hlkasnh iwhg
What is the period block and group of the element with the electron configuration Ar 3d74s2?
the element belongs to 4th period, 9th group, it is a d block element. the element is cobalt
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
What is the electron configuration of the element in the period 3 group 6a?
S [Ne] 3s2 3p4
The period of an element can be determined by what?
The total number of electron shells in an atom has determines its period grouping.
What is a possible electron configuration for chlorine?
Chlorine is the group 17, period 3 chemical element. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p5. Another way to write this is [Ne] 3s2 3p5 since the beginning of the electron configuration is the same as neon's.
What is the full electron configuration that's in group 2 in the fourth period?
The inert gas in Period 2 is the element Neon(Ne). Its electron configuration is 2-8.
Have two valence electrons and get to a stable electron configuration by using two electrons?
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
What is the electron distribution for Na?
The electron configuration of sodium is: [Ne]3s1.
