What was the significant change that Glenn Seaborg made to Mendeleevs periodic table?
Glenn T. Seaborg contibutedto the Periodic Table by discovering 8 different elements. He discovered americium (95), curium (96), berkilium (97), californium (98), einsteinnium (99), fermiuim (100), mendelevium (101), and nobelium (102). Element 106, seaborgium, bears his name.

Why is the mendeleevs table called the periodic table?
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
Is blinking of eyes a non- periodic change?
No, blinking of eyes is a periodic change because it occurs at regular intervals to keep the eyes moist and protect them from debris.
What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
Who started the Actinide family?
From the earlier known chemical properties of Actinium (89) up to Uranium (92), indicating a relation to the transition metals, it was generally assumed that the transuraniums would have similar qualities. During his Manhattan Project research in 1944, Glenn T. Seaborg experienced unexpected difficulty isolating Americium (95) and Curium (96). He began wondering if these elements more properly belonged to a different series than the transition metals, which would explain why the expected chemical properties of the new elements were different. In 1945, he went against the advice of colleagues and proposed the most significant change to Mendeleev's periodic table to have been accepted universally by the scientific community: the actinide series.
How the melting temperature properties generally change as you go from left to right in the periodic table?
The melting temperature properties generally change as you go from left to right in the periodic table by no specific trend/no detail pattern.
What did glen seaborg do?
suceede in making man made elements and proposed a change in the periodic table
What was Seaborg's last major change to the Periodic Table?
Seaborg's last major change to the Periodic Table was the actinide concept. He proposed placing the actinide series below the lanthanide series to create the extended table and highlight the similarities between the two series.
How did later chemists change Mendeleevs periodic table?
They used atomic number instead of Atomic Mass to organize the elements
How did chemist change mendeleevs perioic table in the early 1900s?
Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.
Why is the mendeleevs table called the periodic table?
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
What is non periodic change?
Non periodic change is game and business
Is hatching of an egg periodic or non-periodic?

Is a skateboard a physical change?
No its a chemical change
Is blinking of eyes a non- periodic change?
No, blinking of eyes is a periodic change because it occurs at regular intervals to keep the eyes moist and protect them from debris.
What can a triangle represent in a periodic equation?
In a periodic equation a triangle can be used to represent the given change of something.
How the density properties generally change as you go down the columns of the periodic table?
The density properties generally change as you go down the columns of the Periodic Table by increasing.
