The middle is noble gases the first one is alkaline metals and then the last one is the only one left
Answer:
Repeated experimentation introduced new discoveries.
Explanation:
Science is not a static body of knowledge, scientific theories change as new evidence emerges from repeated experiments.
For many years, the wave theory of light was generally held by almost all scientists.
Further experiments such as photoelectric effect and Compton effect lent credence to the the particle theory of light, hence the answer
Answer:
C: Sodium
Explanation:
Iron had a way higher density neon has way to know as well as carbon and the closest one is sodium
A. x Ray's have the second highest frequency in the light spectrum after gamma rays
About <u>1 in 500,000,000</u> molecules in a glass of water are dissociated.
<h3>What is water?</h3>
Water can be defined as a liquid molecule or chemical compound that typically comprises two (2) main chemical elements in a ratio of two (2) atoms of hydrogen to one (1) atom of oxygen. This ultimately implies that, these two (2) chemical elements include the following:
Water is an amphoteric chemical compound (substance), which ultimately implies that it can accept a proton that is also acting as a base, while also donating a proton that acts as an acid as shown in the balance chemical reaction below:
2H₂O(l) ⇄ H₃O⁺(aq) + OH⁻(aq)
Based on scientific research and experiments, approximately one (1) water molecule in half a billion (500,000,000) dissociate into an OH⁻ ion, especially by losing a proton to another water molecule.
