Senior Congregate Care. What is congregate housing? Congregate housing is an environment thatâs designed to cater for the housing needs of seniors and disabled persons. Residents of a congregate housing complex have private apartments but share a common dining room, kitchen facilities, and other amenities. The purpose of this arrangement is to allow seniors to continue living an independent life although assisted with such tasks like cooking.
The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass.
Dmitri Mendeleyev invented it using inspiration from his favourite game: Patience! In 1955, Element 101 was named Mendelevium in his honour. So he ended up on his own table!Nobody specifically <i>discovered</i> the periodic table of elements, but <b>Dmitri Mendeleev</b> was the one who put it all together. <br /><br /><br /> I think one can do better than that.
