The radioactive element​ carbon-14 has a​ half-life of 5750 years. a scientist determined that the bones from a mastodon had los
Monica [59]
Radioactive elements obey 1st order  kinetics,

For 1st order reaction, relation between rate constant (k) and half life [t(1/2)] is,
k = \frac{0.693}{t(1/2)} =  \frac{0.693}{5750} = 1.205 X 10^-^4 hr^-^1

Also, for 1st order reaction, we have
t = \frac{2.303}{k} log  \frac{\text{initial conc.}}{\text{final conc.}}
 
Given that: <span>the bones from a mastodon had lost 78.5​% of their​ C14,
</span>∴ initial conc. of C14 = 100%, conc. of C14 left after time 't' = 21.5%

∴t = \frac{2.303}{1.205 X 10^(-4)} log \frac{\text{100}}{\text{21.5}} = 1.2758 X 10^4 hours

If an element has 35 electrons and its mass number is 37, what is its atomic number and how many neutrons does it have?. Multi L
Lynna [10]

Answer:

Atomic Number: 35

Number of Neutrons: 2

Explanation:

The number of protons and electrons are the same, so given that this element has 35 electrons, it also has 35 protons.

Atomic number is the number of protons, so it is 35.

Mass number is the number of protons + neutrons, so take the mass number of 37 and subtract the 35 protons to get 2 neutrons.
