The correct answer is B. D-block.
The periodic table is a tabular arrangement of the chemical elements, ordered by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and non-metals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as
assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.The elements in the d-block are those in which the d subshell is being filled. The d-block elements are located in the central part of the periodic table, between the s-block and the p-block elements. The d-block elements are also known as the transition metals.
The elements in the d-block have a wide range of properties. Some of the d-block elements are very reactive, while others are very stable. Some of the d-block elements are metals, while others are non-metals. The d-block elements are also very important in industrial applications.
The element with atomic number 29 is copper. Copper is a transition metal that is found in group 11 of the periodic table.
Copper is a reddish-brown metal that is used in a variety of applications, including electrical wiring, plumbing, and coins. Copper is also a good conductor of heat and electricity.The element with atomic number 29 has 29 protons and 29 electrons. The electron configuration of copper is 1s2 2s2 2p6 3s2 3p6 3d10 4s1. The d-block elements are those in which the d subshell is being filled. In the case of copper, the d subshell is filled with 10 electrons.
The element with atomic number 29 is a d-block element. The d-block elements are located in the central part of the periodic table, between the s-block and the p-block elements. The d-block elements are also known as the transition metals.
