The table below shows two conclusions about atoms based on experiments by Rutherford and Bohr. Name of scientist Experimental Process Conclusion about atoms Rutherford Fire radioactive particles through thin gold foils and detect them on a screen The nucleus is the center of the atom with electrons revolving around it in orbits Bohr Check the spinning motion of electrons Electrons are found outside the nucleus of the atom at various levels called shells, arranged like layers of an onion Which of these statements best explains why Rutherford and Bohr visualized the atom differently? They studied atoms of different elements. They had different focuses in their experimental process. They did not believe in agreeing on a single model of the atom. They did not have instruments to take accurate measurements.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
