2023 Basic Chemistry

Lessons 19-23

QuestionAnswer
What are groups of atoms that act like a single anion called? --ions ---radicals---molecules---photons radicals
What is a force that holds atoms together in a compound? Is it radials--ions chemical bonds or crystals chemical bonds
What is a group of atoms held together by covalent bonds called? ---ions---covets-molecules--electrons? molecules
What is a group of atoms that act like a single anion called? Is it polar---nonpolar-radicals-or a compound? radicals
What is a solid in which particles are in a regular repeating pattern called? --ions--crystals--molecules-protons crysttals
What is the formula for sodium and oxygen? NA2O
What is the formula for flourine and flourine? F2
What is the formula for barium and chlorine? BaCl2
What is the formula for hydrogen and bromine? HBr
What element is this class? Trick question Boron --boooring! Extra credit if you say how much you enjoy chemistry!!
What is the formula for calcium and iodine? CAI2
What is a chemical bond formed by the transfer of electrons from the outer orbit of one atom to the outer orbit of another?--cation--anion-bond angle--ionic bond -covalent bond ionic bond
atom that gains electrons in an ionic bond----cation--anion-bond angle--ionic bond -covalent bond anion
chemical bond formed by the sharing of an electron pair between atoms----cation--anion-bond angle--ionic bond -covalent bond covalent bond
atom that loses electrons in an ionic bond----cation--anion-bond angle--ionic bond -covalent bond cation
angle formed by two covalent bonds----cation--anion-bond angle--ionic bond -covalent bond bond angle
A solid in which particles are in a regular repeating pattern is known as---covalent compound--crystal--radical---nonpolar compound CRYSTAL
the biggest difference between an ionic bond and a covalent bond is-- electrons are shared in covalent bonds and transfered in ionic bonds--only two electrons in ionic bonds-eight electrons are transfered in ionic bonds--covalent bonds are non polar electrons are shared in covalent bonds and transfered in ionic bonds
Which of the following is a example of a radical?--CL- or (PO4)2- or O2- or H+ (PO4)2-
The negative and the positive charges on the ions in an ionic compound always add up to ---8 or 2 or-0 or -1 0
The aluminum ion has a charge of AL+3. The sulfur ion is S-2. The formula for aluminum sulfide is Al3S2 or AIS or AIS3 or Al2s3 Al2S3
What is the difference between a polar covalent bond and a nonpolar covalent bond? In a polar bond, the electron pair is shared equally between the atoms
Tell the kinds and numbers of the atoms in one molecule of ethyl alcohol: C2H5HOH 2 carbons 6 hydrogens 1 oxygen
Amonia NH3,--carbon dioxide-CO2 and water H20 have different shapes. Tell what shapes these molecules have. Explain why each molecule has the shape it does. Nh3 has a pyramid shape. The one unshared electron pair pushes the other covalent bonds together. CO2 has a linear shape. The carbon shares two electron pairs with each oxygen.H20 is a bent molecule- two unshared electron pairs repel each other-OH bonds
What does a molecular formula tell? A molecular formula tells the kinds and numbers of an atoms in a molecule. h20 is a example
What does an ionic formula tell? An ionic formula tells the kind and relative number numbers of in an ionic compound.Na Cl which contains one Na for one Cl is a example
a polyatomic atom is a radical-or photon -- a combination of atoms or a group of covalently bonded atoms that act like a single atom when combing with other atoms - a combination of atoms or a group of covalently bonded atoms that act like a single atom when combing with other atoms
what is a network solid?a covalent substance whose molecules are very large-a photon--the Jerry Seinfield show--a diatomic element a covalent substance whose molecules are very large
