Q: 3s23p5 and t: 4d105s25p5 in the same period

False

Explanation:

Electronic configuration is the short representation of the structure of an atom.

Atomic number = number of electrons = number of protons.  

Example  

Atomic number of phosphorus is 15 so it has 15 electrons. The electronic configuration of Phosphorus is given as

Here the superscript number represents the electrons 2 + 2 + 6 + 2 + 3 = 15 Electrons of Phosphorus.

The elements present in the same group will have same number of valence electrons (outer shell electrons)

For example  

Fluorine,Chlorine,Bromine are all present in the same Group

The electronic configuration are  

The elements present in the same period will have same number of shells

For example  

Sodium, Magnesium, Aluminium, silicon, Phosphorus, sulfur, chlorine, Argon  

All these elements are present in the same 3rd period and the number of shells = 3

The electronic configurations are

it means there are 3 atoms of oxygen

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
