The atomic number of the product decrease by one in the d) positron emission and the e) electron capture radioactive decay. These radioactive decays are two of three common forms of the Beta Decay which occurred when the proton released a positron and a neutron emitted an electron<span>. The Beta Decay can increase or decrease the atomic number.</span>
Answer:
27.216 mg/h.
Explanation:
First you need to convert 100 lb to kg, and there are 45.36 kg, she will receive 10 mcg/kg/min so if you multiply it by 45.36 kg, she will receive 453.6 mcg/min, so in one hour (60 minutes) she will receive 27216 mcg/h, 1000 mcg are 1 mg, so she will receive 27.216 mg/h.
<h2>Total distance divided by total elapsed time gives : Average speed </h2>
Explanation:
Speed
It is the distance traveled by body with respect to time .
Its formula is Speed = distance /time
V=S/T
units : m/sec or Km/hr
Distance
It is total path traveled by body in any direction .
It unit and symbol is : S and unit = m /Km
Average speed
It is the total distance traveled by body with respect to total time taken to travel that given distance .
Average speed = total distance /total time
A.s = T.D/T.T
unit = m/sec or Km/hr
Instantaneous velocity
It is the distance traveled by body at particular instant of time ,in given direction .
Displacement
It is the shortest path traveled by body in given direction .
Answer: B. High precision
Explanation:
Explanation:
Sulfide anion is depicted by S²⁻
Sulfur is an element with atomic number of 16;
In an atom;
there are subatomic particles:
Protons are the positively charged particles
Electrons are negatively charged
Neutrons do not carry any charges.
In a neutral atom, the number of protons and electrons are the same.
In an anion, such atoms have gained electrons.
For sulfide anion, the number of electrons will increase by 2, giving a total of 18 electrons.
The electronic configuration will then be:
S²⁻ = 1s² 2s² 2p⁶ 3s² 3p⁶
