What element two metallic elements that are not silver or grey?
copper and gold
What is the rule for naming compounds with only two elements?
The rule is that the metallic (or the less electronegative) element goes first, and the non-metallic (or more electronegative) element goes second. And the second element has an alteration in its name to indicate the formation of a compound. For example, sodium + chlorine = sodium chloride.
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
The most abundant metallic element on earth?
aluminum that's aluminum for the brits aluminum is the most abundant metal in the earth's crust, it is never found free in nature. All of the earth's aluminum has combined with other elements to form compounds. Two of the most common compounds are alum, such as potassium aluminum sulfate and aluminum oxide About 8.2% of the earth's crust is composed of aluminum."

Element with both metallic and nonmetallic properties?
The items that contain more than one element and have metallic properties are known as alloys. They can be an intermetallic compound that lacks phase boundaries, a metallic phase mixture, or a solid element solution.
Most reactive group in periodic table?
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
Is pewter an element?
No, it's a mixture (or alloy) of two metallic elements, copper and tin.

Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
How many atoms of a Group 17 element would be needed to react with one atom of a Group 2 element Explain.?
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
What is phosphorus an element or compound?
