Answer:
Explanation:
A = A metal that lost three electrons is Z³⁺
Metals loses their electrons and form cations. So when an metal loses three electrons positive three charge is created.
B= A metal that lost one electrons is Y⁺
When metal loses one electron positive one charge is created.
C=A nonmetal that gained one electrons is X⁻
When non metals gain the electrons anions are formed and negative charge is created on atom due to addition of electron. So when non metal gained one electron -1 charge is created.
D= A nonmetal that gained three electrons is V³⁻.
when non metal gained three electrons -3 charge is created, because of addition of three electrons.
Answer:
<u>36 times</u>
Explantaion:
The force exerted between two charged particles is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
In the case of S and q: The distance of separation is 1 unit
F(Sq) α S*q/1²
In the case of S and p: the distance is 6 units
F(Sp) α S*p/6²
therefore:
F(Sq) = 36 * F(Sp)
Answer:
they lie in the same group

Well - it depends on where you start and where you finish on the electromagnetic spectrum. But by most estimates, we're can see about 0.0035% of the electromagnetic spectrum (that includes gamma rays, radio waves, x-rays, infrared, ultraviolet, microwaves, etc.).

Answer:
The atomic mass of phosphorus is 29.864 amu.
Explanation:
Given data:
Atomic mass of phosphorus = ?
Percent abundance of P-29 = 35.5%
percent abundance of P-30 = 42.6%
Percent abundance of P-31 = 21.9%
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass / 100
Average atomic mass = (29×35.5)+(30×42.6) + (31×21.9) /100
Average atomic mass = 1029.5 + 1278 + 678.9/ 100
Average atomic mass = 2986.4 / 100
Average atomic mass = 29.864 amu.
The atomic mass of phosphorus is 29.864 amu.
