Answer: 1st element will have 1 valence electron whereas last element will have 8 valence electrons except in first period in which last element has 2 electrons. Answer. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements. Pb is a main group element in period 6, 14 of the periodic table. n+4/2m-3 find n if the line is parallel to the x axis. The group and period to which this element belongs to is (a) 2nd group, 3rd period (b) 2nd group, 2nd period (c) 3rd group, 2nd period (d) 3rd group, 3rd period. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements. Based on above Figure, the period number of an element is determined by the number of shells occupied with electrons in an atom of that element. This puts Sulfur in […] The other four elements in the group—aluminum (Al), gallium (Ga), indium (In), and thallium (Tl)—are all metals. The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13-18; the transition metals in the columns labeled 3-12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row elements are actinides . This is a list of the 118 chemical elements which have been identified as of 2022. State the period of periodic table to which these elements belong to. Question 7.

Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).The name "pnictogen" is not in common usage; it derived from the Greek work pnigein, "choke" or "stifle," which is a property of breathing pure nitrogen gas. Relationship between the electron arrangement and the period number of an element. And so let's move on to the concept of periods. Which group elements will gain electrons to form negative ions? It is arranged according to the periodic law: Elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern. (b) The given element is Silicon (atomic symbol: Si). Group 5 (by IUPAC style) is a group of elements in the periodic table. Show Answer Tell which element is located in the p-block Elements The number of valence electrons in an element of group 17 = 17 - 10 = 7. Problem 11 Each of the chemically active Period 2 elements forms stable compounds in which it has .

JM Jessica M. Numerade Educator 01:27. Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). (b) Germanium-Group 14 Period 5. Answer (a) 2nd group, 3rd period. As the number of occupied shells is 3 (since electrons are filled in K, L and M shells), the element belongs to third period. An ionic bond is formed between X & Y as a result of transfer of two electrons from X to Y. Question: In the modern periodic table, the element Calcium (atomic number = 20) is surrounded by elements with atomic numbers 12, 19, 21 and 38. A higher atomic weight than the one on its left. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals. Periods are the rows of the periodic table that from left to right increase in order of mass Group 1 Group 1 elements are in the first group of the periodic table with similar properties of being soft and reacting violently with water Mass Mass is the amount of substance that can be measured in grams or kilograms Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Now to find the period we have to understand that the period is the number of shell the element is having therefore here chlorine has 3 shells (K-2, L-8, and M-7). The tantalum element is in group 5 and period 6 of the periodic table. It is stored under water as it is highly reactive when it comes in contact with air. 7. (a) What is the group and period number to which this element belongs? Using the group and period numbers, identify the elements that are located in each of the following location. (4) The physical properties of the elements in group such as melting point, boiling point, density vary gradually. ; Palladium has 46 protons, 46 electrons, and 60 neutrons.
