In the modern periodic table, elements are arranged in

"The modern periodic table consists of elements arranged according to their increasing atomic numbers'. With reference to elements with atomic numbers 1 to 20 only in the periodic table - differentiate them into - metallic elements, metalloids, non-metals & noble gases.

In the modern periodic table, elements are arranged in order of increasing atomic numbers, which is related to the electornic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, s, p,d and f. The modern periodic table consists of 7 periods and 18 groups. Each period begins with the filling of a new energy shell. in accordance with the Aufbau principal, the seven periods (1 to 7) have 2,8,8,18,18,32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthanoids and actinoids, are placed at the bottom of the main body of the periodic table Which of the element whose atomic numbers are given below, cannot be accommodated in the present set up of the long form of the periodic table ?

In the modern period table, elements are arranged in order of increasing atomic number which is related to the electric configuration. Depending upon the type of orbitals receving the last electron, the elements in the periodic table have been diviced into four blocks viz s,p,d and f. The modern periodic table consists of 7 periods and 18 groups. Each period being with the filling of a new energy shell. In according with the Aufbua principle, the seven periods (1 to 7) have 2,8, 8, 18, 18, 32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthanodis and actionoids are placed at the bottom of the main body of the periodic table. Which of the elements whose atomic numbers are given below, cannot be accommodated in the present set up of the long form of the pariodic table?

According to the periodic law of elements, the variation in properties of elements is related to their : atomic masses nuclear masses atomic numbers nuclear neutron-proton number ratios.

Properties of the elements are a periodic function of their _______ . (atomic number/ mass number/relative atomic mass)

In modern periodic table, the element with atomic number Z = 118 will be:

Which of the following statements (s) about the modern periodic table are incorrect ? (i) The elements in the modern periodic table are arranged on the basis of their decreasing atomic numbers (ii) The elements in the modern periodic table are arranged on the basiss of their increasing atomic mases. (iii) Isotopes are placed in adjoining group(s) in the periodic table (iv) The elements in the modern periodic table are arranged on the basis of their increasing atomic number.
