plse make sure these are correct
1.When an atom loses an electron is..
a. becomes a negative ion.
b. becomes a positive ion.
c. forms a covalent bond.
d. gains protons
is the answer D
2.Which of these is a property of an ionic compound?
a. low melting point
b. poor conductor of electricity
c. crystal shape
d. shared electrons
is the answer B
3. A bond in which a pair of electrons is shared between two atoms.
is the answer A
4. Fluorine atoms cannot form a doubel or triple bond because fluorine...
a. is a nonmetal
b. strongly attracts electrons
c. has 7 valance electrons
d. is a gas at room tempiture
is the answer D
5. An ionic crystal splits along a face of
a. like charges
c. unlike charges
d. random ions
plse help me and thx
not sure about the others though.
I don't believe any of the original answers are correct.
Marcie has the correct answer for 1 and 3.
im pretty sure 2 is d.
thx i am like having trouble with this chapter becuase are teacher asigned it and like we didn't really go over the chapter do you happen to know 4 and 5
no sorry...we are doing the same thing in science and we take the test over it tom...we never talked about those things from 4 and 5....i don't really get it either.
thx any ways and good luck on your test;)
thanks...hope you get your other answers
Ionic compounds are formed when a metal loses an electron to a non-metal, which gains the electrons.
Covalent compounds are formed, on the other hand, when electrons are shared between atoms.
atoms gain or lose electrons to achieve what?
1 is b
My science book is exactly the same. this is what I put:
I'm not sure if I am right on some of those, and I'm still looking for the answer for number 5. Hope this helped!
i need number 5 too!!!! im doin the same stuff for hw now
what is the factors of quantity and quality of water?
when an atom loses an electron it becomes a positive ion
A property of an ionic compound is crystal shape
A bond in which a pair of electrons is shared between two atoms is a covalent bond
Fluorine atoms cannot form a doubel or triple bond because fluorine has 7 valence electrons
An ionic crystal splits along a face of like charges
im pretty sure these are all right
i had the same questions for homework but i didn't hand it in yet so i don't know if they're all correct
hope this helps :)
Most of you guys are wrong. Are you taking honors? Cause I got 1.B 2.C 3.B 4.C 5.A
