Answer:

The sulfur S and fluorine F elements will form negative ions.

Explanation:

Ions are molecules that have gained or lost an electric charge. Therefore, they can be positive (loss of electrons) or negative (they have gained electrons), also called cations or anions, respectively.

So negative ions are negatively charged particles that are also called electrons. The elements or particles will gain electrons in order to complete the valence electron octet.

In groups 15 to 17, the charge is generally negative because these elements are more likely to gain electrons than to lose them, thereby reaching a full octet of eight valence electrons.

In this case, <u><em>the elements sulfur S and fluorine F belong to group 16 and 17 respectively. Then these will form negative ions.</em></u>

Answer:

Good Question

see Negative ions are those which gain electrons to attain stability

Now, We know All metals tend to donate electrons which inturn results in positive charge

Now Have a closer look at options

a) F

It is fluorine

it's configuration is 2,7

that means it requires one electron to complete it's octet from 7 to 8

therefore, it will gain one electron which results in

{f }^{ - }

b)Li

lithium is metal having one electron in outermost shell So it will rather loose electron to attain stability

c)Ne

Neon is Noble gas which exists in neutral stare

d)S

Sulphur needs 2 more electrons to attain stability

therefore it exists as negative ion

e)Al

Aluminum is metal So it exists as positive ion

f)Be also exists as positive ion

What is the total amount of heat absorbed by 100.0
sergejj [24]

Answer:

Option (B) 6270J

Explanation:

The following were obtained from the question:

M = 100g

T1 = 30°C

T2 = 45°C

ΔT = 45 —30 = 15°C

C = 4.18J/g°C

Q=?

Q = MCΔT

Q = 100 x 4.18 x 15

Q = 6270J

Therefore, the total amount of heat absorbed is 6270J
