No. 2001 started on a Monday. 2011 started on a Saturday.
Prior to 2011, the last year with the same day-date arrangement was 2005. After 2011, the next one will be in 2022.
1983 is the same as 2001. The person who stated that 1987 and 1998 being the same was wrong... except that they are the same to EACH OTHER, but NOT to 2011.
No element has the exact same election arrangement as another element. However ion can have the same election arrangement as another element. For example Chloride (Cl-) has the same configuration as Argon, and Potassium (I) (K+) also has the same configuration as argon.
no they have to be in the same group
They should all impala's from 2000-2011 have the same bolt pattern 5x115
All of the elements in Period 3, excluding group 18/VIIIA, have the same inside electron arrangement as phosphorus. They all have the electron configuration of neon as their inside arrangement of electrons.
All of the elements in Period 3, excluding group 18/VIIIA, have the same inside electron arrangement as phosphorus. They all have the electron configuration of neon as their inside arrangement of electrons.
Chlorine needs to gain one electron to achieve the same electron arrangement as neon, which has a stable octet (eight valence electrons). By gaining one electron, chlorine will have a full outer shell with eight electrons, resembling the electron arrangement of neon.
Krypton.
A material made entirely out of the same atoms. ie. the atoms all have the same electron arrangement.
ALLOTROPE
An ion of bromine has the electron shell arrangement of 2, 8, 18, 7. Therefore, an atom that has the same electron shell arrangement would be one that has 35 electrons, such as the element bromine itself before it becomes an ion with a charge of -1.
