What element is Ar 4s3d7?
Zinc has this electron configuration.
What is the element with the electron arrangement of 2 and 8 and 7?
Chlorine
How does an element in group 2 attain a stable electron configuration?
It loses 2 electrons and becomes a +2 ion.
How many elements does the outer electron have?
An electron is not an element.
What is the Electron configuration for 12M?
There is no element such as 12M. Assuming that you mean 12Mg, the electron configuration is 2, 8, 2.
Which is the electron configuration of a transition element for the Bohr orbits?
2-2
How many electrons are in the electron cloud of the element carbon?
2
What element is Ar 4s3d7?
Zinc has this electron configuration.
What is the element with the electron arrangement of 2 and 8 and 7?
Chlorine
What element has an electron configuration of 2 8 8 1?
Potassium.
What is the correct electron configuration for the element Zn?
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
What element has 2 electron energy levels and 4 electrons available for bonding in the outermost energy level?
The element carbon
What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
How does an element in group 2 attain a stable electron configuration?
It loses 2 electrons and becomes a +2 ion.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
Which element has 1s 2 2s 2 2p 6 3s 1 as its electron configuration?
Sodium.
