<span>On the periodic table, a group of elements is a column of elements. These columns are also known as families, which indicates that the elements within a group will share certain characteristics. One of these characteristics is the number of valence electrons, or the electrons on the outermost orbit of an atom. So, any element within the same group will have the same number of valence electrons, which will then lead to other shared characteristics, such as chemical properties (how an atom reacts during a chemical reaction, for example). </span>
Answer:
fission
fusion
Explanation:
The two reactions shown are nuclear reactions. There are two main types of nuclear reactions;
1) fission reaction
2) fusion reaction
A fission reaction is said to have occurred when a large and unstable nuclide is bombarded with neutrons thereby causing it to decay into daughter nuclei.
A fusion reaction involves the combination of two light nuclei to yield a heavier nuclei.
In the first reaction, a neutron was used in bombarding a uranium nucleus to yield the products listed on the product side of the nuclear equation. We know this by comparing the sum of the masses and charges on the product side with those on the reactant side in order to decide what the bombarding particle is.
The second reaction involves the fusion of two deuterium nuclei to yield one helium nuclei and neutrons as shown.
The correct answer is A) more powerful than uranium.
Radium is more powerful than uranium.
Radium is part of our environment. It's part of nature, in small amounts. It is part of the alkaline-earth group and was discovered by Pierre and Marie Curie in 1898. Although is soft it has a lot of radiation. When it is exposed to air, it quickly oxidizes. It corrodes in water because it forms radium hydroxide.
