Which two elements are in same period as well as same group of modern periodic table.
. Two elements P and Q belong to the same period of the modern periodic table and are in Group 1 and Group 2 respectively. Snapsolve Two elements P and Q belong to the same period of the modern periodic table and are in. Period 3 elements have an inner electron configuration of Ar.
Two elements P and Q belong to the same period of the modern periodic table and are in Group 1 and 2 respectively. Elements in the same period in the periodic table have the same A. Which two periods have the same number of elements.
Period 4 and period 5 of the periodic table have the same number of elements. Fluorine F and chlorine Cl D. These elements can only hold two electrons both in the 1s orbital.
These are all the same sort of distances from the nucleus and are screened by the same electrons in the first and second levels. Compare their following characteristics in tabular form. While C and D belong to same period 3 rd with three shells.
Elements in the same period have 2 points the same valence electrons but different outer energy levels True False. A period in the periodic table is a row of chemical elementsAll elements in a row have the same number of electron shells. A new element has been discovered and you are on the task force to determine where this new element will be placed on the periodic table with its known properties.
B Their metallic character c The size of their atoms. A The number of valence electrons in their atom. C K forms positive ions when it reacts.
There are 18 elements in each period. What do the elements in Period 3 have in common. Tin Sn and antimony Sb C.
Consider the first two members of period 3. Hello the precise answer would be no such elements exist or discovered as of now. The highest principal energy level of period 4 elements is 5.
Arsenic As and antimony Sb. The table gives some properties of J and K. Number of shells B.
Asked on 30th Mar 2021 a How is the valency of an element determined if its electronic configuration is known. A J forms an acidic oxide. Hence both Be and Li belong to the same period ie 2 nd period.
Which two groups of elements in the periodic table are the most reactive. Ii Elements in a group have same number of valence electrons. In reactions they both tend to lose electrons after all they are metals but sodium loses one electron while magnesium loses two.
9b Given below are some elements of the Modern Periodic Table. However here the element X 2 fills its outermost shell with two electrons and Z 10 with 8 electrons. Arranged this way groups of elements in the same column have similar chemical and physical properties reflecting the periodic law.
Be and Mg have the same number of outermost electrons ie 2. Chemistry questions and answers. Select two elements that belong to the same period.
Thus elements A and B with two shells belong to same period ie. Thus elements A and C belong to same group with 1 valence electron. Hydrogen H and neon Ne B.
D K is more metallic than JSave My Exams. In the whole of period 3 the outer electrons are in 3-level orbitals. Principal quantum number of outermost electron in Be and Li is 2.
Compare their following characteristics in tabular form. Ii The elements which have the same valence shell belong to the same period in the periodic table. Which two elements on the periodic table are in the same period.
Both belong to group 18 noble gas. Which two elements are in the same period. The valence electrons of group 4A elements are in the 5s subshell.
3 J and K are two elements from the same period in the Periodic Table. Which one of the two has bigger atomic size. Determine the valency of an element of atomic no.
Compare the following characteristics in tabular form. There are seven not two other elements in the same period as neon. There are only two elements in the first period.
Period 5 elements all have six 5p electrons. A The number of electrons in their atoms b The sizes of their atoms c Their metallic character d Their tendencies to lose electrons e The formula of. Iii Elements having all shells completely filled belong to 18 th group.
O Sn and Rb O K and Ba O F and Cl O Se and Te 16 17 18 19 sh Support SchoologyE. But technically isotopes can be identified as the same group and same period elements. Two elements P and Q belong to the same period of the Modern Periodic Table and are in Group-1 and Group-2 respectively.
B J is found to the left of K in the Periodic Table. They are lithium beryllium boron carbon nitrogen oxygen and fluorine. Hydrogen and heliumThis is because in quantum physics this period fills up the 1s orbitalPeriod 1 elements follows the duet rule they only need two electrons to complete their valence shell.
Hence both Be and Mg belong to the same group in the periodic table. Which statement about J and K is correct. Hence the metallic characters of elements P and Q is as follows.
Sodium Na and magnesium Mg.
