Why does a mole of copper atoms weigh less than a mole of lead atoms?

Because copper has a smaller molar mass, hence it will have less mass per mole than lead.

What is bigger a sodium atom or a carbon atom?
A carbon Atom. Sodium Atoms Weigh Less Than Carbon Atoms And Also They Are Smaller Overall.
Why is bronze harder than pure copper?
The atoms of pure copper are highly ordered and packed, which allows for a high level of malleability and ductility (meaning it bends easily.) However, if you add in some tin atoms, because tin is a much bigger atom than copper, it restricts the movement of those copper atoms, which overall makes the alloy harder and less "bend-y."
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
Why is zinc larger than copper?
because of inner orbit electron repulsion causing zinc to have a slightly expanded orbit thus less dense
Will gold replace copper from copper sulfate solution?
No, gold is less reactive than copper.
What is heavier 1kg of lead or 1kg of copper?
The lead and the copper will weigh the same. But there will be less lead than copper by volume if both materials are solids. And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight. A kg of lead takes up a lot less room (volume) than a kg of ping pong balls, even though they both weigh the same.
What is the product for the reaction between lead acetate and copper sulfate?
Lead is less reactive than copper, so the sulphate ion would stay bound to the copper, so the answer is the same compounds as you started with.
How many moles are present in 1 g?
It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.
Why a bar of the brass is harder than a bar of copper?
Because brass is an alloy of copper & zinc - the zinc atoms change the geometry of the copper crystals - making it less flexible.

Do protons in a very large nucleus have a greater chance of flying apart?
Sort of... The general tendency is for a larger atom to be less stable. Above a certain point (after lead) no stable atoms are known to exist.Sort of...

Is there a .45 acp with less than 230gr loads?
Yes, you have to look around to find this type of ammo. Usually hollowpoints will weigh less than 230gr because a portion of the lead and copper have been removed to make the hollowpoint. With kinetic energy, there is always a trade off between Mass (~weight) and Velocity. Projectiles that weigh less than 230gr will travel faster, but impact with less force than one weighing 230gr.
Which is heavier lead or solder?
Lead. The densities of lead and tin are 11.34 g/cm^3 and ~7 g/cm^3, respectively. Lead solder is an alloy made of mostly lead and tin; a mixture of lead and tin will weigh less than 100% lead. Lead-free solders are made of tin, copper, silver, indium, bismuth, zinc, antimony, and other metals; none of these metals is heavier than lead. So, lead is the champion.

Does a mole of neon atoms weigh the same as a mole of aluminum atoms?
No. Think of it this way - say you had 20 basketballs and 20 bowling balls. Will the basketballs weigh the same as the bowling balls? No, because an individual basketball weighs less than a bowling ball, so if you have equal numbers of them, they aren't going to weigh the same. Now take 6.02 × 1023 atoms (one mole) of neon and 6.02 × 1023 atoms of aluminum. One atom of neon is going to weigh less than one atom of aluminum, so equal numbers of them aren't going to weigh the same.
Explain Will kg of hydrogen contain more atoms than kg of lead?
Since,1 gram of hydrogen contains= 6.02*10 raise to power 23therefore, 1000 grams of hydrogen contains = 6.02*10raise to power 23 * 1000 i.e 6.02*10raise to power 26!!nd 207 grams of lead contains=6.02*10 raise to power 23therefore 1 gram of lead contains= 6.02*10 raise to power 23 / 207hence .. 1000 grams of lead contais= 6.02 * 10raise to power 23 * 1000 / 207= 29.08 * 10 raise to power 23Hence we can say tht hydogen contains more no. of atoms !!
What weighs more concrete or lead?
Lead has a higher density than concrete, so a 1"x1"x1" cube of concrete would weigh less than the same cube of lead.
