Final answer:
An element with atomic number 119 would be classified as a nonmetal and placed in Period 7 of the periodic table. However, it would not have a full valence shell of electrons and would not be placed in Group 1.
Step-by-step explanation:
Based on periodic trends, it is most likely that an element with atomic number 119 would be classified as a nonmetal. Elements on the right side of the periodic table tend to be nonmetals.
Since the periodic table is divided into periods based on the energy levels or shells of the elements, this element would be placed in Period 7. Periods refer to horizontal rows on the periodic table.
The valence shell of an element is the outermost shell that contains electrons. For an element with atomic number 119, it is unlikely to have a full valence shell of electrons since it would require a very high number of electrons. Therefore, this statement is not true.
Lastly, Group 1 elements are alkali metals, which appear in the first column of the periodic table. The element with atomic number 119 would not be placed in Group 1 as it is expected to have a high atomic number.
