Question

what is charge in silicate ion in Si2O7 power n

Answer 1

The charge of silicate ion in Si2O7 is+7

Answer 2

The charge of silicate ions is -6.

Silicon and oxygen make up most of the Earth’s crust. They form the basis of a class

of minerals called silicates. All silicates and analogues are derived from the silicate

ion, SiO4

The silicon atoms can be replaced by other metals to form analogous compounds, notably the aluminosilicates in which aluminium atoms partially replace

the silicon atoms.
