The periodic table of the elements are describe the electronic configuration of the elements on which the properties of the elements depends. Among the given groups only metal, non-metal and semi-metal group are the part of periodic table. The metallic property depends upon the binding energy of the electrons with the nucleus. Thus the elements which have the valence electrons more near to the nucleus that is s-block elements are more metallic in nature. On the other hand the elements which have the valence electrons far from the nucleus are more non-metallic in nature like p-block elements. However the binding energy or the attraction of the outermost electrons to the nucleus depends not only its valence electrons position but also some other factors like shielding effect, effective nuclear charge etc.
The elements which are in between the metals and non-metals can be classified as semi-metals.
Although the conductivity of a material is an inherent property of the metals but sometime the nonmetals or semi-metals are also behave like a conductor due to presence of the other elements, thus it cannot be a p[property of the periodic table. Similarly acidity, flammable gases are not part of the periodic table.
The mass of 2.88 × 10²² molecules of Bi (NO₃)₃ is 678.854 grams.
<h3>What is mass?</h3>
Mass is the quantity of matter in a physical body. Mass can be calculated by dividing the molar mass by the mass of the moles of the substance.
The molar mass of Bi (NO₃)₃ is 1461.99 g/mol
The molecules here is 2.88×10²²
The number of molecules will be divided by 6.023 x 10²³
2.88×10²² / 6.023 x 10²³ = 4.781 moles
Putting the value in the equation
mole = mass/molar mass
mass = moles x molar mass
4.781 x 1461.99 = 678.854 grams
Thus, the mass of 2.88×10²² molecules of Bi (NO₃)₃ is 678.854 grams

Answer:
This is hilarious, every time I ignite, they feed me water, little do they know this heat will defeat, and hydrogen only makes me stronger!
Explanation:
When Hg is burning, it uses the oxygen from H2O and turns it into hydrogen gas, and that contributes to the burning.
Answer:
Some credit goes to user sness!
