After an atom has lost an electron it becomes a/an ________ and has a ________ charge.    

Rutherford’s scattering experiment with gold foil demonstrated the existence of a nucleus containing both protons and neutrons.

It is now possible to know the exact location of an electron in an atom.

Which of the following is not a state function?  

A radio wave has a frequency of 8.6 × 108s-1. What is the energy of one photon of this radiation? (3 min.) h = 6.6262 x 10-34 J s c = 3.00 x 108 m/s    

  phosphate PO4-3 phosphite PO3_3 Perchlorate ClO4-1 Permanganate MnO4-1   Choose the letter that shows the correct formula for the compound formed between copper (II) ion and the phosphide ion.A)  CuPO4       B)  Cu2PO4      C)  Cu3(PO4)2   D)  Cu3P2        E)  CuP 

Isotopes are atoms of the same element with the same number of electrons.

Calculate the density of CO2(g) at 100.°C and 10.0 atm pressure. (4 min.) R = 0.0821 L atm/ mol K C = Carbon = 12.011 g//mol O = Oxygen = 15.999 g/mol

The relationship between the energy and wavelength is direct.

Calculate the heat absorbed when 28.6 g of water is heated from 22.0°C to 78.3°C (specific heat of water = 4.184 J/(g·K)). 1 J = 1000 kJ. 4 min.
