Dobereiners triads were groups of elements with similar properties that were identified by the German chemist Johann Wolfgang Dobereiner.
. Which two elements most likely have the most similar properties. But a diagonal relationship exists between certain pairs of diagonally adjacent elements in the second and third periods. 6 Why do group 2 elements form 2 ions.
Elements with similar properties are organized in groups of the periodic table. 1 1s22s22p4 2 1s22s22p5 3 Ar4s23d104p3 4 Ar4s23d104p4. Lithium and sodium D.
F and Cl are Halogens. Na Mg Al and K are metals. People also ask why do elements in the same have.
Neon and argon B. View solution View more. 1 Na and Ca.
Helium and argon b. Which two elements have similar properties and 8 electrons in their outermost shells. 1 beryllium and magnesium.
Fluorine and chlorine C. Argon and krypton THE ANSWER IS D. Which two elements have similar properties and 8 electrons in their outermost shells.
What is such an arrangement of elements called as. 2 rows Which two elements have the most similar chemical properties. Cl and Ar are not in the same group Ar is a noble gas and is very inert unlike Cl.
Lithium and sodium C. Dobereiner stated in his law of triads that the arithmetic mean of the atomic. The mass of Y is approximately equal to the average mass of X and Z.
The number of elements in between X and Y respectively are. The elements of the same group have similar chemical properties because they have the same number of valence electronsThe given elements are not from the same groups. CLASSES AND TRENDING CHAPTER.
Which two elements have the most similar chemical properties. The Fish Tale Across the Wall Tenths and Hundredths Parts and Whole Can you see the Pattern. 1 beryllium and magnesium.
They dont form solid hydrogen carbonates but react with nitrogen to form nitrides. 2 hydrogen and helium. Calcium and strontium C.
F Na Mg Al Si P S Cl Ar K a Pick two sets of elements which have similar properties. F Na Mg Al Si P S Cl Ar K a Pick two sets of elements which have similar properties. 7 Why do group 2 elements never form m3.
Two elements A and B have similar chemical properties. Chlorine and bromine B. The second column on the periodic table of the chemical elements is collectively called the alkaline earth metal group.
Both elements appear on the same group IIand therefore have. Which two elements have similar chemical properties according to the periodic table. Give one example of such a set of elements.
4 Why does group 2 elements have similar properties. X and Y are two elements having similar properties which obey Newlands law of octaves. Click again to see term.
8 Why do group 2 elements lose 2 electrons. Which two electron configurations represent elements that would have similar chemical properties. Beryllium magnesium calcium strontium barium and radium.
Arsenic and Antimony B. K and Ca - are in the first and the secong group respectively and they differ per instance in their bonding with F - KF and CaF. Click card to see definition.
B The given sequence represents which law of classification of elements. Tap card to see definition. Neon and Argon B.
As you descend the Group the metal the element becomes more reactive. These are the first 20 elements in the periodic table. 5 Why do group 2 have similar properties.
3 phosphorus and sulfur 4 potassium and strontium. Use the periodic table to select the element that best fits each of the following descriptions. Correct answer to the question Which two elements have similar properties and 8 electrons in their outermost shells.
A and B respectively are. Iodine and Bromine D. For example Sodium potassium lithium rubidium and caesium have similar chemical properties.
Therefore Elements with similar chemical properties have D the same number of electrons in an outermost shell as the elements in the same group only have the same number of electrons in the outermost shell. Given set represent Mendeleevs law of periodicity. Nitrogen and phosphorus D.
3 What charge do all elements in Group 2 have in common. Sodium and Potassium C. Li and Na are in the same group and have very similar properties.
B The given sequence represents which law of classification of elements. Fluorine and Chlorine D. The arrangement of these elements is known as Dobereiner triad.
Which solution below most likely shows a vivid color. He observed that groups of three elements triads could be formed in which all the elements shared similar physical and chemical properties. These make two sets of elements.
The other metals in Group I are lithium potassium rubidium and francium. Elements have been arranged in the following sequence on the basis of their increasing atomic masses. Because the outer electron structure in all of these elements is similar they all have somewhat similar chemical and physical properties.
The three elements A B and C with similar properties have masses X Y and Z respectively.
