True
What else can I help you with?
Most of the elements are solids true or false?
True. The majority of elements on the periodic table are solids at room temperature and pressure.
True or false most elements are nonmetal?
Most elements are metals.
Ions are randomly arranged in ionic solids true or false?
False. Ions in ionic solids are arranged in a specific repeating pattern known as a crystal lattice, rather than randomly.
True or false mendeleev also grouped elements that has similar properties?
True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.
True or false Au is the symbol for gold on the periodic table of elements?
True. Au is the symbol for gold on the periodic table of elements.
Most of the elements are solids true or false?
True. The majority of elements on the periodic table are solids at room temperature and pressure.
True or false most elements are nonmetal?
Most elements are metals.
Are all pyramids are platonic solids true or false?
False
Are all elements in group 14 solids?
It is true, all are solids.
For atoms of most elements the outer energy is filled when it has 8 electrons true or false?
true
Very few minerals are compounds true or false?
False. Most minerals are compounds, which means that they are combinations of elements. Additionally, some minerals are elements by themselves.
Solids having flat surfaces that form into polygons are polyhedrons true or false?
true
Ions are randomly arranged in ionic solids true or false?
False. Ions in ionic solids are arranged in a specific repeating pattern known as a crystal lattice, rather than randomly.
Is it true that all elements are gases?
It is false.
Did Mendeleev group elements that had similar properties true or false?
It is true.
Is the sentence true or false the fact that copper wire can be bent shows that some solids do not have a definite shape?
False. The ability of copper wire to be bent does not necessarily indicate that some solids do not have a definite shape. Solids, including copper, have a definite shape but can still be flexible or malleable under certain conditions.
Is the basic particle from which all elements are made is a molecule true or false?
False elements are made up of atomsFalse.
