All lat/longs on all maps would agree. That spheroid, derived from satellite measurements of the Earth, is GRS80, and the WGS84. datum matches this spheroid.
Alkali and Alkaline Earth Metals
cdn1.byjus.comAtomic and ionic radii Being the first element of each period, alkali metals have the largest atomic and ionic radii in their respective periods. On moving down the group, there is an increase in the number of shells and, therefore, atomic and ionic radii increase. The monovalent ions (M+) are smaller than the respective parent atoms as expected.

igppweb.ucsd.eduThe local earth radius is given by † re(j)= cos2j a2 + sin2j c2 Ê Ë Á ˆ ¯ ˜ -1/2 where j is latitude, and a and c are the equatorial (6378 km) and polar (6357 km) radii, respectively. The look angle of the radar depends only on the local earth radius re, the range to the sphere r, and the height of the spacecraft above the center of the ...
