Social Activities    

During your studies there are plenty of opportunities to hang out with your fellow students: for example, six parties take place throughout the year, a gala and other kinds of social gatherings. Furthermore, we have sports activities, an annual play, two camps and a “birthday” week (Dies) full of activities in May. Furthermore, there is a Master's Club organising activities especially for master students. Of course you can also join the other Proton activities. All activities can be found here. 


Apart from recreational activities where members can relax, Proton also organises study related events, like lectures and excursions to companies to give students an insight into their career perspectives. The foundation Proton International organises an international trip. During this trip, various chemical companies and universities are visited in order to get students acquainted with chemistry abroad. 
In addition to these trips, Proton organises the PAC symposium together with the chemistry student associations from Amsterdam and Leiden. At this symposium a lot of foreign and domestic orators gather to give lectures on various topics in chemistry.
Apart from organising a wide range of activities for her members, Proton also has her own magazine called ‘De Chemograaph’. Chemistry related articles, interviews with professors and reports of Proton activities are examples of what can be found in this magazine.

Career Orientation    

Proton organises many activities which allow you to orient on what you can do after obtaining your master’s degree. Throughout the year there are lunch lectures during which a company informs you about their core tasks and job possibilities. Also a Career Day will be organised where alumni of Utrecht University tell more about their career paths. So Proton has a lot to offer when it comes to your career! 

The Department    

Proton has a close relationship with the Department of Chemistry, which results in a broad cooperation between the two. The commissioner of education of the association is also a member of the department board and coordinates the student representation of the education. For more information, send an e-mail to
