The option that is the structural units that make up ionic solids is option D. Ions
What are ionic solids?Ionic solids are made up of ions, which are atoms or groups of atoms that have a positive or negative charge due to the gain or loss of electrons. In ionic solids, the positive ions (cations) are typically formed by metal atoms, while the negative ions (anions) are typically formed by nonmetal atoms. The ions in ionic solids are held together by electrostatic forces of attraction, called ionic bonds.
Therefore, These bonds are formed when the electrons from the outermost energy level of the metal atom are transferred to the outermost energy level of the nonmetal atom, creating a stable compound.

what is the difference between quantative and qualitative analysis
Answer:
I guess quantitative data is countable or measurable, relating to numbers; qualitative data is descriptive, relating to words. Quantitative data lends itself to statistical analysis; qualitative data is grouped and categorized according to themes.
Explanation:
Answer:
quantitative - actual numbers as data
Qualitative- uses senses (taste, touch, etc.)
Explanation:
If an atom has 7 valence electrons, what will its charge be when it becomes an ion?
Answer:
Well, he needs to take one more electron to have a stable structure. And by doing that the atom will have more electrons than protons and will turn into a negative ion.
How do the mass number and atomic change as a particle goes through beta decay
Answer:
The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus

Microorganisms have a major role in maintaining soil biodiversity. They recycle nutrients in ecosystems and decompose organic matter in soil. Organic matter contains dead and living plant and animal materials. Microorganisms convert these materials into simpler compounds that maintain soil quality and help with plant growth.
Which solution could best help to restore or increase microorganisms and soil biodiversity?
A.
adding manure or compost to the soil
B.
spraying chemical weed-killers and fertilizers on the soil
C.
removing all ground-covering plants from the soil
D.
adding sewage containing synthetic materials to the soil
Answer:
A i think
Explanation:
The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.
What are microorganisms?A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
“Microorganisms are minute organisms that are invisible to the normal eye.” Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc.
Given options are-
A. adding manure or compost to the soil
B. spraying chemical weed-killers and fertilizers on the soil
C. removing all ground-covering plants from the soil
D. adding sewage containing synthetic materials to the soil
Therefore, The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

Look at the diagram below, which shows an atom of an element. How many valence electrons does it have? Based on this, would the atom be reactive or unreactive?
1. The number of valence electrons the atom have is seven (7).
2. The atom is reactive
1. How do i determine the number of valence electron in the atom?
Valence electron is simply defined as the number of electron(s) present in the outermost shell of an atom.
Considering the diagram given from the question, the number of electrons in the outermost shell is seven (7).
Thus, we can conclude that the valence electron the atom have is seven (7)
How do i know if the atom is reactive or not?From the diagram given, we determine that the number of valence electrons present is 7. This means that the atom required 1 more electron to complete its octet configuration.
Thus, the atom will be very reactive in order to quickly attain a stable configuration.

However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing.

Body systems are like runners in a marathon, who each run alone and don't need the other runners to finish the race, is not a good way to describe a body system, hence option B is correct.
How body systems work together?Your digestive tract takes nutrients and water from the food you eat in to your body. The body's cells receive oxygen, water, and nutrients through your circulatory system.
Your skin, excretory system, and respiratory system all function to remove wastes from your cells.
Your body's many systems depend on one another to function properly. While your heart's muscles require oxygen from your lungs to beat, your respiratory system depends on your circulatory system to distribute the oxygen it collects.
Therefore, option B is correct.
