Why did Dmitri leave blank on the preodic table?
There is no specific reason mentioned for why Dmitri Mendeleev left blank spaces on the periodic table. It is believed that he left these spaces to accommodate elements that were yet to be discovered or to demonstrate the existence of elements with certain properties that were predicted but not yet confirmed. These blank spaces eventually led to the discovery of new elements and validated Mendeleev's periodic table.
What is the 4th element in the periodic table of elements?
calcium
What are the elements in the preodic table that exist as graphite?
Carbon is the main element that exists as graphite in the periodic table. Graphite is a form of carbon where the atoms are arranged in layers that can slide over each other easily, giving it its lubricating properties.

Where is the category found in the periodic table?
the left side of the preodic table consistes of metals, the right side is of non metals, the middle ones are transition metals.
Elements in the preodic table which forms a basic oxide?
Elements on the left side of the periodic table, such as alkali metals like sodium and alkaline earth metals like calcium, tend to form basic oxides. These elements have low electronegativity and readily lose electrons to form positively charged ions, which react with oxygen to form basic oxides.
What is the 4th element in the periodic table of elements?
calcium
