<u>Answer: </u><em>B. Adding more protons to a positively charged body until the number of protons matches the number of electrons</em>
Option B is the appropriate response
<u>Explanation:</u>
Utilising the equivalent number of inverse charges will kill a charged body.
Adding more protons to a decidedly charged body until the number of protons coordinates the quantity of electrons won't kill the body since protons are emphatically charged particles. Adding more protons to an emphatically charged body would make it all the more decidedly charged.
Enabling free electrons to escape from a contrarily charged body will kill since the more negative body leaves the negative electrons.
Answer:
a. Azane
b. sulphur hexachloride
c.carbon tetrachloride
d. Carbon disulfide
e.Umbelliferone
f.Disilicon hexabromide
g. Dinitrogen trifluoride
h.
Answer:
An Atom
Explanation:
An atom is the smallest unit of matter
Bohr display says obviously the electron spins around the core in orbit. so circle implies a circular locale around core.
Answer
Density = 7.87g/cm^3
Explanation:
Density is the ratio of mass of the given object to the volume of the object, in this question iron is the given object, then we make use of atomic number of iron
Given:
Length= 287pm = 287*10^-10cm
Atomic mass of Fe= 56.0u
Z=2(for body centered cubic unit cell)
Avogadro number (N 0)=6.022× 10^23
Density= ZM/a^3 × N
Where
Z= body centered cubic unit cell
Then substitute
N= Avogadro's number
a=Length
Density = (2× 56)/(287*10^-10cm)^3 × (6.022 × 10^23)
Density = 7.87g/cm^3
