Discussion Overview

The discussion revolves around identifying true statements about elements in the periodic table, focusing on properties of metals and nonmetals. It includes homework-related inquiries and interpretations of the statements provided.

Discussion Character

  • Homework-related
  • Debate/contested

Main Points Raised

  • Post 1 asserts that most elements in the periodic table are metals, thus claiming statement A is false, while B is considered true due to the similar properties of metallic elements.
  • Post 1 also argues that statement C is true because metals are more numerous, suggesting they are more diverse, which is challenged in subsequent posts.
  • Post 1 claims statement D is false, noting that helium is not a diatomic molecule, and states that E is false as fewer than six elements are liquids at room temperature.
  • Post 2 questions whether the similarity of properties among metals applies to nonmetals, prompting further discussion.
  • Post 3 suggests that if most metals are alike, then they might be less diverse than nonmetals, which contradicts Post 1's claim about statement C.
  • Post 6 introduces the idea that some metals float on water, implying that statement B could also be false, though this is described as nitpicking.
  • Post 7 expresses frustration with the homework system and mentions that help received suggested B alone or B and C as true, but ultimately indicates uncertainty about the answers.
  • Post 8 reveals that a technical error was the cause of confusion regarding the answers.

Areas of Agreement / Disagreement

Participants express differing views on the truth of statements B and C, with no consensus reached on which statements are definitively true. The discussion remains unresolved regarding the accuracy of the claims.

Contextual Notes

Participants rely on interpretations of the properties of metals and nonmetals, and there are unresolved assumptions about the definitions of diversity and similarity in properties.

Pick the "TRUE" Statements?

Homework Statement



Which of the following are true statements ?

a) Most of the elements in the periodic table are nonmetals.

b) The metallic elements have similar properties: they conduct electricity well, are ductile and have high densities.

c) Nonmetals are much less diverse in their physical properties than metals are.

d) Fluorine, bromine and helium are all diatomic molecules.

e) Only about six of the elements in the periodic table are liquids at room temperature.

Homework Equations


chem ones lol

The Attempt at a Solution



alright here's my answers:

A. I got was false because most of the elements are metal.
B. I got was true because they all do have similar properties.
C. I got was true because there are more metals, so the metals are more diverse.
D. I got was false because Helium is not a diatomic molecule.
E. I got was false because there are less then 6 elements which are liquids at room temperature.

so my answer for which ones were true is B&C . . . but it keeps telling me I am wrong.

Help Please?

As you have said in B - all metals are alike. Does it hold for non-metals?

That would be my line of thinking.

Some metals float on water, so even B can be false. But IMHO that's nitpicking.

lol they can't all be false becuse then you wouldn't even have to put in an answer . . its part of an online thing I am doing and i even went to the help room in which they told me to try B alone or B & C. But they said more likely just B was the only TRUE answer so idk . .

any other ideas?
 


Turns out there was ANOTHER technical error, thanks 4 the help
