Which of the following statement(s) is/are true? In the Modem Periodic Table, the arrangement of elements is based on their: Statement 1:increasing atomic number in the horizontal rows. Statement 2:increasing atomic number in the vertical columns.

Which of the following statement(s) is/are true? In the Modem Periodic Table, the arrangement of elements is based on their: Statement 1:increasing atomic number in the horizontal rows. Statement 2:increasing atomic number in the vertical columns. Correct Answer Only 1

The correct answer is Only 1.

  • In the Modem Periodic Table, the arrangement of elements is based on their increasing atomic number in the horizontal rows.
  • The Modem Periodic Table is used to predict the properties of elements.
  • Even the properties of those elements can be predicted which have not yet been discovered.

Key Points

  • Elements in the modern periodic table are arranged in 7 periods and 18 groups.
  • Horizontal rows are called periods and vertical columns are called groups.
  • According to their shared physical and chemical properties, the elements can be grouped into the major categories of metals, metalloids and nonmetals.

Consider the following statements regarding the Mendeleev periodic table. Identify the correct ones. Elements were arranged in increasing order of atomic weights in horizontal rows called 'groups' and vertical columns called ''periods'.

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
