Thomson in 1897 was the first to suggest that one of the fundamental units was more than 1,000 times smaller than an atom, suggesting the subatomic particle now known as the electron. Thomson discovered this through his explorations on the properties of cathode rays.
That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation<span> that relates wavelength and frequency for electromagnetic waves is: λν=c where </span>λ<span> is the wavelength, ν is the frequency and c is the speed of light.</span>
Answer:
The He₂ 2+ ion is more stable since it has a higher bond order (bond order = 1) than the He₂ + ion (bond order = 1/2).
Explanation:
Molecular orbital of He₂⁺
There are two electrons in bonding and 1 electron in antibonding orbital
Bond order = 
= 
Molecular orbital of He₂⁺²
There are two electrons in bonding and 0 electron in antibonding orbital
Bond order = 
= 1
So bond order of He₂⁺² is 1 which is more stable than He₂⁺ whose bond order is .
I believe the correct answer is option A. Paré.
Or otherwise known as Ambroise Paré. He was considered one of the "fathers of surgery" for modern forensic pathology. And was known to be a pioneer in surgical techniques on the battlefield using medicine, mostly in the treatment/healing of wounds.
Hope I could help! :)
Answer:
MgCl₂(aq) + Al₂(CO₃)₂(aq) --> MgCO₃(s) + AlCl₃(aq)
Explanation:
Magnesium Chloride - MgCl₂
Aluminium Carbonate - Al₂(CO₃)₃
Magnesium carbonate - MgCO₃
Aluminium Chloride - AlCl₃
The equation of this reaction is given as;
MgCl₂(aq) + Al₂(CO₃)₃(aq) --> MgCO₃(s) + AlCl₃(aq)
