Question

Checking my answers? please help
1)The loss of valence electrons from an atom produces an anion.

A. True
B. False

false


2)Nonmetals typically react by gaining electrons to attain noble gas electron configurations.

A. True
B. False

False

Answer 1

first one ur right
but why the second its false

Answer 2

What is the number of valence electrons in an atom of Al?



A. 13

B. 3

C. 10

D. 8
The answer is B ?

Answer 3

yaa its 3:)

Answer 4

im confused on number 2

Answer 5

its true :) bcoz oxygen is eager to have two electron with it and hence so Nitrogen needs three electrons to have/attain the noble gas configuration hence its true :)

Answer 6

Among the following, the element with six valence electrons is?
a. C.
b. Cs.
c. O.
d. Ne.

is c. O. correct?

Answer 7

yup :)

Answer 8

Which of the following molecules has one lone pair of electrons?

a. CH4
b.HCl
c.H2O
d.NH3

Its d right?

Answer 9

yaaaaaaa ur right LOL:)

Answer 10

The nonmetals in Groups 5A, 6A, and 7A


A. lose electrons when they form ions.

B. form positively charged ions.

C. form ions with charges of 3–, 2–, and 1–, respectively.

D. form ions with a numerical charge equal to their group number.
im stuck between c and d?? im thinking its c?

Answer 11

In general, how do metals react?
A. Losing valence electrons
B. Gaining valence electrons
C. Sharing valence electrons
D. Sometimes gaining and sometimes losing valence electrons

A?

Answer 12

Yes its is A......metals are electropositive in nature....they readily lose thier elctrons to attain octet......losing electrons is easier than gaining electrons to reach octet state...
