Answer:
1. Fluorine (7 electrons) => c. steals 1 electron
2. Calcium (2 electrons) => a. gives away 2 electrons
3. Oxygen (6 electrons) => d. steals 2 electrons
4. Lithium (1 electron) => e. gives away 1 electron
5. Xenon (8 electrons) => b. neither gives away nor steals any electron
Explanation:
Given the following valence electrons of the atoms listed above, each atom can be matched to its corresponding number of electrons it can steal or give away as they form bonds and attain a stable state:
1. Fluorine (7 electrons) => this will steal 1 electron from another atom to attain a stable state when it comes to make the number of electrons 8.
2. Calcium with 2 valence electrons, will give away this 2 electrons in its outer shell to be stable and form bond with another atom that will accept these 2 electrons.
3. Oxygen with 2 valence electrons, will steal 2 electrons to make the electrons in its outer shell 8, as it bonds with another atom to become stable.
4. Lithium will give away 1 electron to become stable when it combines.
5. Xenon with 8 electrons in its outer shell is in a stable state and kind of inert. It doesn't need to receive or steal any electron from or to any other atom in this state.
Answer:
Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.
Answer:
The changes which can be reversed are called reversible changes. These are also called physical changes. Example- Melting of ice, Tearing of paper etc are physical or reversible changes.

Answer:
Data is used to evaluate the treatment that is provided to the patient in each episode of nursing diagnosis.
Explanation:
An outcome measure is a tool that is used to assess the current status of the patient that is influenced by the nursing interventions. It is marked by the status of the resolution for individual nursing diagnosis as being either resolved or not.
The data collected by outcome measures supports in establishing the foundation for providing the correct medical treatment to the patient. Which later helps to assess the treatment provided to the patient. It provides reliable and credible justification for the treatment on an individual patient level.
Below are a few examples of these outcome measures;
- Mortality
- Timeliness of care
- Safety of care
- Patient Experience
- Effectiveness of care
