The elements atomic number, the number of protons in the necules
Solid state of matter
- the atoms are tightly packed in orderly form, they slightly vibrate but are stuck in a fixed position. Solids cannot be compressed and they maintain their shape
<span>The answer is true that Group 1A elements (except for hydrogen) are the
alkali metals. Groups 2A are alkaline earth metals. Group 3B-12B are transition
metals. Group 3A to 4A except Boron, Carbon, Nitrogen, oxygen, silicon,
phosphorus, sulfur, germanium, astatine, selenium, antimony, tellurium, polonium
are basic metal. Carbon, nitrogen, oxygen, phosphorus, sulfur and selenium are
nonmetals. Boron, silicon, germanium, astatine, antimony, tellurium and polonium
are metalloids. Groups 7A are halogens. Groups 8A are noble gases. The lower
part of the periodic table are lanthanides and actinides.</span>
Answer: Yes, a given amount of Hydrogen would react with different masses of the two isotopes of chlorine, and no, this does <em>not</em> conflict with the Law of Definite proportions
Explanation:
About 76% percent of Cl is found in the Cl-35 isotope, and about 24% in the Cl.37 isotope. that means that about 24% of Cl nuclei have 2 more neutrons than the average Cl nucleus.
So, if 
reacts with 
, 76% of the Hydrogen that reacted will react with Cl-35, and the rest will react with Cl-37. Why does this not conflict with the law of definite proportions? Because each Hydrogen atom ends up paired to a single Chlorine atom! Moreover, the proportion of Cl-35 to Cl-37 remains constant in all samples of Chlorine that are naturally found, thus we will always find the same proportion of Chlorine to Hydrogen in any HCl sample we come across. Thus the weight of a mol of Cl will always be 
or 35.45 if we had done this calculation with more significant digits.
Therefore 1 mol of (2 grams) will always react with 1 mol of (35.45g*2=70.9 grams), and this is a definite proportion.
Answer:
the positive charges of the nuclei and the negative charges of delocalized electrons
Explanation:
The interatomic forces that joins a piece of metal atoms together are the positive charges of the nuclei and the negative charges of delocalized electrons.
This bond type is the metallic bond.
- The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice.
- Also, the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
