No. Slavic languages are spoken in Eastern and Southern Europe. Russia is considered the mother of Slavic languages, and could be considered as part of Northern Europe, in which case this would make Slavic languages the most common in Northern Europe. However, Russia is included in Eastern Europe, and therefore, Slavic languages are not even present in Northern Europe (natively). If speaking by splitting Europe into just northern and southern regions, then Russia would be in Northern Europe, and Slavic languages would be the predominate language family in the area. Northern European countries' languages typically are not present outside their own borders. For example, Danish is only common in Denmark, Norwegian in Norway, Swedish in Sweden (and is official in Finland, although spoken by a minority), Finnish in Finland, and Icelandic in Iceland. And if Northern Europeans do learn a second language, it typically isn't one of their neighboring countries. The most common second languages in Northern Europe are English and German. Russian influence does not flow into the Nordic countries, except possibly in Finland, where Russians most recently held control.
The Romance languages are mainly spoken in Southern Europe, including countries like Italy, Spain, Portugal, France, and Romania. These languages evolved from Latin and share common linguistic roots.
The Celtic languages are part of a group called the Italo-Celtic branch of the Indo-European family of languages, which arose somewhere in Eastern Europe.
