Seaborgium is a man made chemical element, radioactive, unstable, atomic number 106, placed in the group 6 and period 7 of the Periodic Table of Mendeleev. Sg is a metal, solid with a formidable predicted density; it is a member of the transactinides family.
All the physical properties of seaborgium are only predicted, not experimentally determined:
- electron configuration: [Rn]5f14.6d4.7s2
- density: 35 g/cm3
- first ionization energy: 757,4 kJ/mol
- empirical atomic radius: 132 pm
- crystalline structure: body centered cubic
The predicted valences are 6, 5, 4, 3, 0; seaborgium is a homologue of wolfram.

Nutrition facts is chemical composition of a food.
cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
Chemical changes take place on the molecular level
Vanadium is a chemical element with the symbol V and atomic number 23. It is a transition metal with a silvery-gray appearance. Some of its key physical and chemical properties include being relatively hard, having a high melting point, and forming various oxidation states in compounds.
Scientists can compare and classify matter based on its chemical properties such as reactivity, flammability, and ability to form bonds with other substances. Physical properties such as melting point, boiling point, density, and conductivity also provide valuable information for classifying matter. By studying these properties, scientists can identify similarities and differences between different substances to categorize them accordingly.
Nobelium is an artificial chemical element, solid, metal, actinoid, radioactive, unstable. Any physical property of nobelium was measured (excepting nuclear properties of the isotopes); some properties are only estimated. Probably nobelium is a reactive metal but we haven't sufficient material for a study and also No is very unstable.
False. A boiling point is a physical property of a substance, not a chemical property. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Boiling point is the temperature at which a substance changes from a liquid to a gas at a given pressure, which is a physical characteristic.
A chemisist can be defind as a physical chemist or a chemical physicist. This means a scientist that explores chemical problems and tries to explain them using fundamental physical principles. I would also add to this definition a chemist that doesn't enjoy remembering random facts!
That is what I wanted to know, this is what i think? Some Physical changes: -You can shape lead -It dislovels Some Chemical changes: -It does NOT burn -It turns into Lead Oxide Those are some but I need help with the rest... and takers? This might also help you... Phyical-You do the change. Chemical-It changes it's self.
A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure and specific physical properties. A rock, by comparison, is an aggregate of minerals and need not have a specific chemical composition. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms.
