ANSWER ASAP PLEASE! (you have to fill in the blank lines) Balance the following equation:
_Fe + _O₂ --> _FeO₃

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

Write balanced nuclear equations for the formation of five elements whose atomic number is between helium (2) and iron (26):

How does the electron-cloud model describe electrons?
