What else can I help you with?
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Is it true that the properties of a compound depend more on which elements are present and less on the structure of the molecule?
No, the properties of a compound depend on both the elements present and the structure of the molecule. The arrangement of atoms within a molecule can greatly influence its properties, such as reactivity, polarity, and overall behavior. Different compounds with the same elements but different structures can exhibit different physical and chemical properties.
What element has both metallic and nonmetallic properties?
We generally refer to these elements as semiconductors. There is something akin to a "diagonal line of elements" in the periodic table that separates the metals from the nonmetals. Elements on the left of this diagonal are metals, and elements on the right are nonmetals. The elements that make up this diagonal are boron, silicon, germanium, arsenic, antimony, tellurium, polonium, and astatine, and they have both metallic and nonmetallic properties. awesome mean something good.
What elements do elements and compounds have in common?
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
What is the similarities in the modern periodic table and Mendeleev's table?
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
What are some properties of a mixture?
Made of elements compounds, or both No change in oringinal properties of components Seperated by physical means Formed using any ratio of components
What are some properties of mixture?
Made of elements compounds, or both No change in oringinal properties of components Seperated by physical means Formed using any ratio of components
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Elements that have properties of both metals and nonmetals?
Metalloids
Why do carbon dioxide and diamond both have different properties?
Different names, different elements, different properties.
Are noble gasses elements with metallic and non metallic properties?
No. Noble gasses are elements that rarely, if ever form chemical bonds. The elements with both metallic and nonmetallic properties are the metalloids.
What elements have similar properties to Aluminum?
it is phineas and ferb
What is classification for the elements that have properties of both metals and non metals?
Elements that have properties of both metals and nonmetals are classified as metalloids. Metalloids have properties that are intermediate between metals and nonmetals, such as being able to conduct electricity but not as effectively as metals. Examples of metalloids include silicon and arsenic.
Do elements in a compound keep their own properties?
No, elements in a compound do not retain their individual properties. When elements chemically combine to form a compound, they create a new substance with distinct physical and chemical properties that differ from those of the individual elements. For example, sodium and chlorine are both reactive elements, but when they combine to form sodium chloride (table salt), the resulting compound has properties that are entirely different from those of the separate elements.
Why do the properties of elements change when they are mixed in compounds?
The act of bonding repositions the electrons, which changes the base properties of the united molecule. It is for this reason, for example, that oxygen O2 has different properties than ozone O3 even though both compounds only have the element of oxygen.
Is metalloids a type of element?
Yes, metalloids are elements that have properties of both metals and nonmetals.
Is it true that the properties of a compound depend more on which elements are present and less on the structure of the molecule?
