A piece of metal is composed of atoms. Each atom in the metal contains 29 protons. How is the metal classified?

The piece of metal composed of 29 protons in its atom is classified as a transition metal.

TRANSITION METAL:

Transition metals are a group of elements on the periodic table categorized for having an incompletely filled d- orbital. Transition metals include copper, cobalt, nickel, chromium, manganese etc. The number of protons of an atom is the same as its atomic number, which can be used to identify an element. According to this question, an atom contains 29 protons meaning that the atomic number of the element is 29. Copper is the element with atomic number 29 and it is classified as one of the transition metals on the periodic table.

A transition metal

Explanation:

The metal is classified as a transition metal or transition element.

In particular, this atom is Copper it has an atomic number of 29 which we know by the number of protons.

The number of protons in an atom is the same as the atomic number.

The element can be found in the d-block on the periodic table. Generally, it is classified as a transition metal. A neutral atom of this element has 29 electrons.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
