What is the Lewis dot structure for Cu?

Answer 1

Cu and it needs to have 11 dots around the Cu

Copper is an exception to electron configurations. It is has a partially filled 4s orbital and a full d orbitial

[Ar] 4s13d10 instead of [Ar] 4s23d9

therefore, the dot diagram would be Cu with one dot, because there is only 1 electron in the 4s.

Answer 2

Au, Cr, Cu, Mo, and Ag all have irregular electron configurations that make the atom more stable.

This would be the anticipated electron configuration for Au

Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f^14 5d^9 Short-hand version: [Xe] 6s^2 4f^14 5d^9

Note: The "^" symbol means the the following number is in the form of a superscript.

This is the correct electron configuration.

[Xe] 6s^1 4f^14 5d^10

Consider how that these elements exist naturally with some (+) charge.

Answer 3

A dot diagram tells you the number of valence electrons. The PT tells you that in the number at the top of the column. Silver is in group 1B and has one valence electron, and therefore one dot.

Answer 4

Since the actual shapes of structure of molecules is 3-dimensional and is not easy to

represent on paper, Lewis gave the idea of drawing structures of elements with

their symbols surrounded by valence electrons. These valence electrons are represented

by dots and hence this concept came to be known as Lewis dot structure theory.

Answer 5

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2, 4d10, 5p6, 6s2, 4f14, 5d9

Answer 6

It will only have one electron on the outside.

Answer 7

Its Au with one single dot around it due to it having only one valence electron

Answer 8

Gold only has once valence electron, so the dot structure starts with the Au atom. One side a single dot is drawn.

Answer 9

Au is the symbol for the element gold.
