The periodic table is an arrangement of the chemical elements, ordered by atomic number, into families, and by doing so illustrates the periodic properties of the elements. Considering the organization of the periodic table, which element would make a good conductor of electricity? What properties of that element would support this choice? A) Copper, Cu. A solid metal that is ductile and malleable. B) Calcium, Ca. A very reactive commonly found Earth metal. C) Silicon, Si. A metalloid that acts as either a metal or a non-metal. D) Mercury, Hg. A dense, liquid metal that moves easily with changes in temperature. no explanation needed thank you :)
Solution 1
According to the properties by which elements are arranged in periodic table,copper which is a solid metal that is ductile and malleable is a good conductor of electricity.
What is an element?
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Answer:
There are several ways to know if a chemical change has occurred. The following is an indication that a chemical change has occurred
1. Change of composition - wood turning to ash when burned.
2. Change of color - For example, during titration, we know that the reaction has occurred by a change in colour from orange to pink when we used methyl orange as indicator., rusting of iron.
3. Change in temperature or energy, such as the production (exothermic or loss endothermic) of heat.
4. The decomposition of organic matter for example, the decay of dead plant or animal
5. Light and/or heat given off: For example, potassium react explosively with water releasing a large amount of heat
6. When the change is difficult to reverse. For example, after burning wood to produce ash, we can not get back the wood again.
Answer:
313.5 L of Br2 contains 8.428x10^24 atoms
Explanation:
Imol of Br2 occupies 22.4L
Therefore Xmol of Br2 will occupy 313.5L i.e
Xmol of Br2 = 313.5/22.4 = 14moles
1mole of Br2 contains 6.02x10^23 atoms.
Therefore 14moles of Br2 will contain = 14x6.02x10^23 = 8.428x10^24 atoms
Therefore 313.5 L of Br2 contains 8.428x10^24 atoms

Answer: 2.44 x10²⁴ atoms Ag
Explanation: solution:
Convert mass of Ag to moles then convert moles to atoms of Ag using Avogadro's number.
437 g Ag x 1 mole Ag / 108 g Ag x 6.022x10²³ atoms Ag / 1 mole Ag
= 2.44x10²⁴ atoms Ag
