Cool liquid from 314 K to 273 K, freeze liquid at 273 K, and cool solid to 263 K.
Copper ions, nitrate ions, and water is in the beaker
They will most likey group with the second group. Since they have 6 electrons and want to have a full outer shell so therefore would group with the second group.
Which of the following measurements is expressed to three significant figures?
C. 5.60 km
Hope this helps!
Proton number = the atomic number (which is the smaller number
neutron number = the mass number (the bigger number) - the atomic number
number of electrons = the atomic number - the charge (it depends on the element but group 1 is +1 group 2 is +2 group 3 is +3 group five is -3 group six is -2 group seven is -1
i would solve the whole thing but its unclear hope this helps tho
