Do gold and silver have similar properties?
A review of the table shows that gold and silver are very similar to each other. Platinum and palladium are likewise similar. Generally, compared to platinum and palladium, gold and silver have a lower melting and boiling point, are better conductors, softer, more reflective, and more abundant.
What is the difference between silver and gold?
Appearance. Gold jewelry is yellow in appearance, and silver jewelry has more of grey tone. Yet there is more to the appearances of these pieces than the basic colors.
What is the difference between Pokemon Silver and Gold?
In Gold, you can catch different pokÃ©mon than in Silver. In Silver, the levels of Ho-oh and Lugia are different from Gold. Then Gold has different graphics than Silver. You all know in Silver, Lugia is level 40 and Ho-oh is level 70, and in Gold, it’s the other way around, right?
What do copper silver and gold have in common?
In the case of copper, silver and gold, these form a vertical triad, called Group 11, within the group of transition metals. They are also found together at the foot of the reactivity series, which means that the metals are not easily oxidised to form positive ions.
Which metal is heavier gold or silver * 1 point?
The answer is gold, which is why smaller gold objects feel heavier when compared to silver objects of the same size. Therefore, gold has a density of 19.32 g/cm3 whereas silver has a density of only 10.49 g/cm3. Thus, a 1 oz bar of gold will be almost half as large as a 1 oz bar of silver.
Which is heavier an atom of gold silver or copper?
At 19.3 g/cc, it is nearly twice as heavy as silver, and even lead. Gold has atomic number 79, atomic weight 197.2, and density 19.32 g/cc. Its single naturally-occurring stable isotope has mass number 197. The electron configuration has one 6s electron outside a filled 3d shell in the ground state, just like copper.
Are gold silver and copper highly reactive?
Alkali Metals are very reactive. This group includes iron, gold, silver, chromium, nickel, and copper, some of which are also noble metals. Poor Metals are fairly soft, and most are not used very much by themselves. They become very useful when added to other substances, though.
Why is gold and silver less reactive?
silver(e.g) is a good conductor of electricity because of its sea of delocalised electrons between the layers of metal ions. However it is not highly reactive because you would need a lot of energy to break the metallic bonds within each of those layers.
Which of these is the most reactive metal?
What metals are non reactive?
Stainless steel and tin (including tin-lined copper) are examples of nonreactive metals. You can use these pans for all kinds of foods, though you may not get the heat conductivity of copper or cast iron.
Which of the following metal is least reactive?
Which of the following is more reactive?
Fluorine is the most reactive element among the given elements.
Which is more reactive in nature?
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. Because alkali metals are so reactive, they are found in nature only in combination with other elements.
Which is more reactive Zn or Cu?
Zinc is more reactive than Cu and Fe metal. Iron displaces copper from its solution. Therefore, copper is less reactive than iron. Copper does not displace any metal therefore it is the least reactive.
What makes an element more reactive?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.
What is meant by reactive element?
In chemistry, reactivity is a measure of how readily a substance undergoes a chemical reaction. The most reactive elements and compounds may ignite spontaneously or explosively. They generally burn in water as well as the oxygen in the air. Reactivity is dependent upon temperature.
Which is more reactive O or S?
oxygen is only more reactive than sulphur because due to small atomic size oxygen atom has high tendency to attract the electrons ( more electronegative )….
Which element in each pair is more reactive I O or S?
Answer. Answer: (1) O is more reactive.
Is oxygen more reactive than selenium?
Oxygen, sulfur and selenium are all group 16 elements. So, their electronegativity decreases down the group. Also, nitrogen is less electronegative than oxygen atom. Hence, we can conclude that out of the given options element oxygen is more reactive than the others.
