Which valences have the greatest tendency to form ions

Biology
2 answers:
jarptica [38.1K]3 years ago
6 0

Answer;

+1,-1,+2,-2,+3,-3

Explanation;

-Valence is the number of electrons lost or gained to complete an element's outer energy level.

-When an atom gains or loses a valence electron, it forms an ion. Atoms form ions in order to help another to obtain a full octet and to stabilize the valence.

-Some atoms gain or lose electrons to form ions because they need to become more stable. They sometimes give them to have an outer shell or gain them to get a closer charge to eight.

A client is admitted to the emergency department after a train derailment. the primary health care provider orders staff members
aleksley [76]
I thin the the emergency staff member that should provide the care for the client is the Emergency Medical technicians. 
These are the appropriate staff who would monitor and track vital signs, perform basic wound care, and also ensure spinal immobilization, as these are basic life support interventions. The paramedics are qualified to perform advanced life support measures. The prehospital care providers on the other hand are the first care providers who help in transportation to the emergency department. Lastly the Emergency medicine physicians recicieve specialized expertise and training  in emergency client management.
