Scientists use potassium-argon method to determine the age of a rock sample. three separate tests showed the rock to be 2.5 billion years old. however, scientists know the rock must be less than 1.25 billion years old based on the rocks around it. how is this possible?
the rock is sedimentary, but is included in an igneous rock formation.
the rock is igneous, but has been weathered, eroded, and incorporated into younger sedimentary rock layers
the radiometric dating was off due to loss of daughter isotopes.
the radiometric dating was done incorrectly.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
