There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110.
However, There is an element with Atomic Mass of 238, it is an isotope of Uranium
NB .
Atomic Number refers to
#1 the position in the Periodic Table
#2 the number of protons in the element
#3 the number of electrons in the neutrally charged element.
Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element.
An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.

What is the Highest atomic number on the Periodic Table?
The element provisionally named ununoctium, believed discovered in 2003, has atomic number 118 in Period 7, column 18, with an atomic weight of 294. Once confirmed, it will be given its permanent element name.
How do you calculate how many neutrons there are in an atom?
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
