Answer:
metal atoms lose electrons to form positive ions (cations)
Explanation:
metal atoms lose electrons to form positive ions (cations ) non-metal atoms gain electrons to form negative ions (anions )
<span>C. compounds that have the same atoms arranged in the same order, but with different three-dimensional orientations.</span>
Answer:
They both have the same number of atoms
Explanation:
The number that indicates the amount of particles in a compound is the Avogadro's number (NA).
It does not matter the mass of compound we have, If we have 1 mol we will be sure that we are talking about 6.02×10²³ particles
6.02×10²³ represents the amount of atoms in twelve grams of 12-pure carbon and it is considered a reference to measure the amount of all kinds of substances present in a given system.
In a metallic bond, atoms of the metal are surrounded by a constantly moving "sea of electrons". This moving sea of electrons enables the metal to conduct electricity and move freely among the ions.
A. A group of related objects that do not send out or receive feedback and cannot modify themselves
Explanation:
An open-loop system is a a group of related objects or systems that cannot send out or receive feedback and modify themselves.
- It is a non-feedback system.
- In this system, the output control system has no effect on whatever input that is fed into the system.
- Output and input in such systems are independent of one another.
- The input and output has no control whatever on each other.
