Which elements have the most similar properties?
Which elements have the most similar chemical properties? Magnesium, strontium, and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties. But the other given elements do not lie in same group so they have different chemical properties.
What determines the main chemical properties of an element?
- Such now-familiar industrial materials as aluminium, silicon, nickel, chromium, magnesium, and tungsten
- Reactive metals such as lithium, sodium, potassium, and calcium
- The halogens fluorine, chlorine, bromine, and iodine
- Gases such as hydrogen, oxygen, nitrogen, helium, argon, and neon

What two elements have the most similar chemical properties?
Step 1. Elements with similar properties are organized in groups of the periodic table. Cl and Ar are not in the same group, Ar is a noble gas and is very inert unlike Cl. Li and Na are in the same group and have very similar properties.
What are 3 elements that have similar chemical properties?
One such grouping includes lithium (Li), sodium (Na), and potassium (K): These elements all are shiny, conduct heat and electricity well, and have similar chemical properties.
How do you tell which elements are most similar in chemical properties?
0:001:193.3f Using the Periodic Table to identify similar elements - YouTubeYouTubeStart of suggested clipEnd of suggested clipSo we need to use the periodic table to do this. So elements that are most similar to rubidium areMoreSo we need to use the periodic table to do this. So elements that are most similar to rubidium are going to be in the same group okay in this case in Group one or one.
Which pair have the most similar chemical properties?
A diagonal relationship exists between certain pairs of diagonally adjacent elements in the second and third periods. ... For example, pairs lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si) exhibit similar properties. ... Thus, Magnesium and Lithium have similar properties.
What are similar chemical properties?
Elements with the same number of valence electrons have similar chemical properties.
Which of the following have similar chemical properties?
Isotopes have same electronic configuration as they have same atomic number. Thus they have similar chemical properties. Hence the correct answer is option A. Isotopes.
What is chemically similar?
Chemical similarity (or molecular similarity) refers to the similarity of chemical elements, molecules or chemical compounds with respect to either structural or functional qualities, i.e. the effect that the chemical compound has on reaction partners in inorganic or biological settings.
Which two elements will have similar physical and chemical properties?
Sodium and potassium share similar physical and chemical properties because they are in the same family or group called Alkali metals. Both will have the same valence electrons and they are both very reactive.
Which element on the periodic table has chemical properties that are most similar to those of carbon?
Silicon is the closest element to carbon in the group, so they have the most similar properties.
Which elements are chemically most similar?
UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : Zr and Hf are chemically most similar, they have same atomic size. Hence, they are known as twins of the periodic table.
Which pair of elements do you expect to be most chemically similar?
Answer and Explanation: The answer is d. Br and I. Elements under the same group have the same number of valence electrons or electrons found in their outermost energy...
Which of the following pair is chemically similar?
F and Cl are chemically similar Hence, we can conclude that elements in the same group of the periodic table have similar properties because they have same number of valence electrons. Only Florine (F) and chlorine belong to same group and thus are chemically similar.
Which element has a half life?
Some of these elements, notably bismuth (atomic number 83), thorium (atomic number 90), and uranium (atomic number 92), have one or more isotopes with half-lives long enough to survive as remnants of the explosive stellar nucleosynthesis that produced the heavy metals before the formation of our Solar System.
What are the two elements that are found in the universe?
The lightest chemical elements are hydrogen and helium, both created by Big Bang nucleosynthesis during the first 20 minutes of the universe in a ratio of around 3:1 by mass (or 12:1 by number of atoms), along with tiny traces of the next two elements, lithium and beryllium. Almost all other elements found in nature were made by various natural methods of nucleosynthesis. On Earth, small amounts of new atoms are naturally produced in nucleogenic reactions, or in cosmogenic processes, such as cosmic ray spallation. New atoms are also naturally produced on Earth as radiogenic daughter isotopes of ongoing radioactive decay processes such as alpha decay, beta decay, spontaneous fission, cluster decay, and other rarer modes of decay.
How many protons does carbon have?
Thus, all carbon isotopes have nearly identical chemical properties because they all have six protons and six electrons, even though carbon atoms may, for example, have 6 or 8 neutrons. That is why the atomic number, rather than mass number or atomic weight, is considered the identifying characteristic of a chemical element.
What are the main articles of isotopes?
Isotopes. Main articles: Isotope, Stable isotope ratio, and List of nuclides. Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus ), but having different numbers of neutrons. Thus, for example, there are three main isotopes of carbon.
What is the atomic number of an element?
Main article: Atomic number. The atomic number of an element is equal to the number of protons in each atom, and defines the element. For example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6. Carbon atoms may have different numbers of neutrons; atoms of the same element having different numbers ...
What is an element?
The periodic table of the chemical elements. In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nucle i. Unlike chemical compounds, chemical elements ...
What is the difference between pure and isotopically pure?
In chemistry, a pure element means a substance whose atoms all (or in practice almost all) have the same atomic number, or number of protons.
