Element x forms an acidic, covalent oxide. Which row shows how many electrons there could be in the outer shell of an atom of x?.
When an element forms an acidic, covalent oxide, it means that the oxide compound formed is covalently bonded and acidic in nature. This typically occurs when the element forms a compound with oxygen, in which the oxygen atoms share electrons with the element to form a covalent bond.
The acidic nature of the oxide is determined by its ability to donate hydrogen ions (protons) in aqueous solution.
The number of electrons in the outer shell (valence shell) of an atom of the element is related to the chemical properties of the element, including its ability to form covalent bonds and its acidic or basic nature.
In general, elements in Group 16 (also known as the oxygen group) of the periodic table, such as oxygen (O), sulfur (S), and selenium (Se), tend to form acidic covalent oxides. These elements have 6 electrons in their outer shell and form compounds with oxygen by sharing two electrons with each oxygen atom, resulting in the formation of a double bond. This results in the formation of acidic covalent oxides, such as sulfur dioxide (SO2) and selenium dioxide (SeO2).
In conclusion, the number of electrons in the outer shell of an element that forms an acidic covalent oxide is related to the chemical properties of the element and its ability to form covalent bonds with oxygen.

thread-safe shared bounded queue
A data structure called a thread-safe queue is made to offer thread safety in a concurrent context. It is a data structure that enables concurrent enqueuing and dequeuing of elements from the same queue across many threads.
The internal structure of the queue ensures that the threads do not interfere with one another, hence the threads do not need to be synchronized. This makes it possible for several threads to access shared resources in a secure and effective manner.
When many threads must access a shared resource in multi-threaded applications, thread-safe queues are frequently utilized. The threads can safely access the queue without synchronization by utilizing a thread-safe queue. As a result, it is more effective and less prone to mistakes.
Thread-safe queues can be used to distribute work among various threads, making them helpful for jobs that must be completed concurrently.
