Answer:
I speak English can someone translate
Explanation:
Searching for this question, I found the options on the internet.
"1.<span />Two atoms share electrons so they can fill their outer shells<span>2.The constant motion of electrons and the creation of charge imbalances bonds two molecules together3.A hydrogen atom with a slight positive charge is attracted to a negative charge of another molecule or atom4.One atom loses one or more electrons and the other atom gains one or more electrons"
The correct answer would be number 1. A covalent bond is achieved when two atoms share electrons from their outer shell so that they have a full outer shell leading to the electronic configuration balance they need.</span>
Answer:
Radioactive dating
Explanation:
Radioactive dating measures the ratio of C¹²(normal) and C¹⁴ (radioactive) in fossils to determine the exact age of the specimen. C¹⁴ is unstable and has a half life of 5730 years, so as the organism ages the amount of C¹⁴ diminishes but the amount of C¹² remains constant. The ratio of C¹⁴ to C¹² is used to analyze the decay of atomic particles to determine exact age.
It becomes charged and is called an ion. Gaining an electron gives it a negative charge.
