Answer: The difference between an element and a compound is that an element is a pure substance that is made of only one element, but a compound is 2 or more elements together
Explanation:
Answer:b
Explanation:
I just answered it on apex
Light Spectrum:
Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio
I'm guessing green means the color wave
So it should be: Radio-Infrared- Green - UV - Gamma
This is because frequency decreases when going from left to right on the Light Spectrum!
Answer:
Explanation:
The graph of an inversely proportional relationship displays a vertical asymptote at the y-axis as the y value increases without bound as x gets closer and closer to zero (but is positive) and decreases without bound as x gets closer and closer to zero (but is negative)and a horizontal asymptote at the x-axis as y gets .
We have that
- The Element with 49 protons is Indium
the isotope symbol in the one-line format
- We have that this is a cation
From the question we are told
An ionic isotope has 49 protons, 50 electrons, and 55 neutrons.
• What is the name of the element?
What is the isotope symbol in the one-line format (e.g., hydrogen-2)?
Is this a cation or is this an anion? Explain how you know.
Generally
Generally an isotope is an a variant form of a element bearing different number of Neutrons but same Proton
Therefore
For an isotope with 49 protons, 50 electrons, and 55 neutrons.
- The Element with 49 protons is Indium
the isotope symbol in the one-line format
- We have that this is a cation
