What else can I help you with?
What elements would it be easier to remove two electrons from?
The halogens (group 17) and the alkali metals (group 1) combine to make full-shell compounds. The noble gases, group 18, already contains full shells and does not bond easily because of this.
What are the alkali metals and coinage metals?
Alkali metals are group 1 metals such as lithium, sodium, potassium, rubidium, cesium and francium. Coinage metals are metals used in coin age to make coins. They are copper, gold and silver.
Why are the elements of group IA called alkali metals?
yes you are true. we call them alkali metals.
Oxides react with oxygen and water and are used to make paints are some of the properties of which type of metals?
Transition metals exhibit these properties. They are known for forming oxides that react with oxygen and water, and are commonly used in various applications such as making paints due to their diverse reactivity and stable oxidation states.
What is special about the Alkali and Alkaline metals?
Alkali metals (Group 1) and alkaline earth metals (Group 2) are notable for their high reactivity, which increases down the group, making them highly reactive with water and air. Alkali metals have one valence electron, while alkaline earth metals have two, leading to their distinct chemical behaviors. Both groups are characterized by low densities and melting points relative to other metals. These properties make them essential in various applications, including batteries, fireworks, and metal alloys.
When 2 metals are mixed together does this make a compound?
No: Two metals mixed together form a special kind of homogeneous mixture called an "alloy".
Do acids and metals react to make oxygen?
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.
What elements would it be easier to remove two electrons from?
The halogens (group 17) and the alkali metals (group 1) combine to make full-shell compounds. The noble gases, group 18, already contains full shells and does not bond easily because of this.
What two metals when mixed together make bronze?
Tin and copper.
What is iron mixed with to make iron oxide?
oxygen
What 2 things make metals corrode?
oxygen and water
Explain why other elements are often mixed with metals to make alloys?
Alloys have improved features compared with single metals.
Which set of elements make up the reactive group of all metals?
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
What metals are mixed with 24 carat gold to make 9 carat and 18 carat gold?
9 carat gold is typically mixed with metals such as copper, zinc, and silver, while 18 carat gold is commonly alloyed with metals like copper, silver, and palladium. These alloying metals help to make the gold more durable and increase its hardness.
Why is gold always mixed with other metal to make jewelry?
If gold wasn't mixed with other metals the jewelry would be too soft to wear.
What can silicon mix with?
Silicon can mix with other elements such as carbon, oxygen, hydrogen, and metals like aluminum and iron to form various compounds and alloys. These combinations allow silicon to be used in a wide range of applications from electronics to construction materials.
Lanthanides are mixed with more common metals to make?
alloys
