Silver is located in Period 5 and Group 11 (Ib) of the periodic table. Group 5A includes Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi).Sometimes group 5A is known as Group 15 or Group VA, it just depends on the periodic table you are viewing. Phosphorous is placed in group 15 period 3. c) Carbon is tetravalent and it is the basis for all the organic compounds in nature. Using the group and period numbers, identify the elements that are located in each of the following location. So know we easily understand that the group is 7 because the no of valence electrons is 7. So the period of the given element is 3. (b) Two elements of the same group. This group lies in the d-block of the periodic table. (a) increases. The element in group 15 and period 4 = As c. The element in group 2 and period 3 = Mg d.

On moving from left to right in a period in the periodic table, the size of the atom. periodic table: table of the elements that places elements with similar chemical properties close together. 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 The main group elements of the periodic table are groups 1, 2 and 13 through 18. 2x= 10 . A higher atomic weight than the one on its left. Carbon belongs to the second period and Group 14. The elements in this group are also known as the chalcogens or the ore-forming elements because many elements can be extracted from the sulphide or oxide ores. Also all the elements of group 1 have one valence electron. Question. 8+3x=5 verbal sentence. If atomic number of carbon is 6, the atomic number of silicon is (i) 7 (ii) 14 (iii) 24 (iv) 16.
