Explanation:

Step1: Identify alkali - metals

Alkali metals are in group 1. Since J has more energy levels than U, U is in period 1 and J is in period 2. So U is in the first - row, first - column and J is in the second - row, first - column.

Step2: Identify T

T has 4 valence electrons on the 3rd energy level. Elements in the 3rd period with 4 valence electrons are in group 14. So T is in the third - row, group 14.

Step3: Identify M

M is a metal in period 3 with 2 valence electrons. Elements in period 3 with 2 valence electrons are in group 2. So M is in the third - row, group 2.

Step4: Identify X

X has one proton, so it is like hydrogen. It is in the first - row, first - column (but we already have U as an alkali metal in the first - row, first - column. In the context of this fictional table, we place it according to the logic of the problem).

Step5: Identify Q

Q has 2 energy levels, is a non - metal and is a solid at room temperature. Carbon in the second period is a non - metal solid at room temperature. So Q is in the second - row, group 14.

Step6: Identify L

L is a noble gas that doesn't have 8 valence electrons. Helium is a noble gas with 2 valence electrons. So L is in the first - row, group 18.

Step7: Identify Z and Y

Z and Y are in the nitrogen family (group 15). Y is a gas at room temperature. Nitrogen is a gas at room temperature. So Y is in the second - row, group 15 and Z is in the third - row, group 15.

Step8: Identify D and R

D has an ending electron distribution of \(s^{2}p^{5}\), which are halogens. R has an ending electron distribution of \(s^{2}\), which are group 2 elements.

Step9: Identify G

G has 6 valence electrons. Elements with 6 valence electrons are in group 16.

Step10: Identify V and W

V and W have full outer energy levels. V has 3 energy levels, so V is a noble gas in period 3 (argon). W is a noble gas in period 1 (helium, but we already have L as helium, so assume it's a different fictional noble gas in period 1).

Step11: Identify A and E

A has 3 valence electrons and E has 6 valence electrons, both in the second period. A is in group 13 and E is in group 16 of the second period.

Step12: Identify K

K has one fewer total electrons than V. Since V is argon (18 electrons), K has 17 electrons.

Step13: Identify I

I has 3 valence electrons on the third energy level. I is in the third - row, group 13.

Answer:

The full placement of symbols on the periodic table requires a visual representation. But based on the above - described steps, each symbol can be placed in its appropriate position on the 1 - 18 element periodic table layout provided in the problem. For example, U and X (hydrogen - like) in the first row, first column (U as alkali metal takes precedence in this fictional context), J in the second row, first column, L in the first row, group 18, Q in the second row, group 14, T in the third row, group 14, M in the third row, group 2, Y in the second row, group 15, Z in the third row, group 15, D as halogen in appropriate period (from electron configuration), R in group 2, G in group 16, V in the third row, group 18, W in the first row, group 18 (different from L in this fictional setup), A in the second row, group 13, E in the second row, group 16, K with 17 electrons in appropriate position, I in the third row, group 13.
