I did this already and i put this down :3 <span>first you would separate each part of the beach into three zones one for basic cleaning another for harder work and then animal searching and cleaning and release, after that you would begin to work on the sections one by one using certain tools and a large amount of effort being used, then finally you end with a cleaned up beach clean water and safe animals and happy faces from people as well.</span>
<em>Hydrogen possesses fewer valence electrons than lithium</em>.
Answer: False.
Explanation: H and Li are both in Group 1. They both have one valence electron.
The Lewis dot structure for aluminum includes the symbol "Al" and a total of three dots around the symbol.
Answer: True.
Explanation: The Lewis structure for Al is ·Al:
<em>An atom's electron affinity value indicates how favorable it is for the atom to form a negatively charged ion.
</em>
Answer: True.
The electron affinity is the energy absorbed or released when a neutral atom gains an electron. The more energy that is released, the more stable the ion,
<em>The name of the ion P³⁻ is phosphoride ion</em>.
Answer: False
Explanation: The name of P³⁻ is phosphide. The stem name of phosphorus in binary ionic compounds is “<em>phosph</em>-.”
You can apply Charles' Law.
V1= 5.00 (L)
T1= 92.3 + 273 = 365.3 (K)
T2= -37 + 273 = 236 (K)
V2 = ? (L)
We have: V1/T1 = V2/T2
--> V2= (V1*T2)/T1 = (5*236)/365.3 = 3.23 (L)
Answer:
neutrons
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
Thus both C14 and C12 have same number of protons as they have same atomic number.
The difference in the mass number of both the isotopes is sue to the difference in the number of neutrons.
Atomic number = Number of protons = 6
For CC- 14, Number of neutrons = 14 - 6 = 8
For C 12, Number of neutrons = 12 - 6 = 6
