Answer:
A. dense
Explanation:
b. Carbon, atomic number 6
c. Neon, atomic number 10
d. Fluorine, atomic number 9
Answer:
Neon, atomic number 10, is stable.
Explanation:
Valencia electrons are the electrons found in the last electronic layer (called valence orbitals). These electrons are what determine the ability of the atom to form bonds. When an element joins another, it does so through its valence electrons.
The noble gases include the elements of group 18 of the periodic table. The noble gases are characterized by their very low chemical reactivity because they are very stable. This is because they have the full valence layer (complying with the octet rule, that is, they have 8 electrons at their last energy level, with the exception of helium that has 2 electrons), causing them to have a low tendency to capture or release electrons . That is why they are also called inert gases.
The Neon, whose atomic number is 10, belongs to the group of noble gases. So this element is stable.
The scientists use one of their five senses to gather information, they are making an observation.
The active gathering of data from a primary source is observation. Observation of living things makes use of the senses. Using scientific tools to perceive and record data is another way that observation may be used in science.
A technique for gathering information through observation of individuals, situations, or physical qualities as they are occurring naturally.
Using one or more senses, our observational abilities provide us with knowledge about things, occasions, attitudes, and occurrences. Being able to see and learn about the outside world is crucial because it forms the basis of effective communication.
Thus, option A is correct.

In scientific endeavors, when one of the five senses is used to gather information, it constitutes making an observation. Observations can involve both qualitative and quantitative data, and they provide evidence that scientists use to form conclusions.
When scientists use one of their five senses to gather information, they are A. making an observation. Scientists usually perform observations by using one or more of their five senses to gain an understanding of the properties or behaviors of a substance or a system. These data can be qualitative (descriptive) or quantitative (consisting of numbers). For instance, seeing a plant growing (observation) and measuring its growth over weeks (data collection). From these observations, the scientist can infer conclusions based on the evidence collected. In brain studies, the activity in the brain during specific tasks is observed, which could be the basis for conclusions about brain functionality.

b. shape
c. size
d. shape and volume
At a constant temperature and pressure, liquids retain their volume of matter.
Matter is defined as total mass which occupy in space, all the physical structures are composed of matter, it can be present in three basic states such as solid, liquid, and gas.
The atoms are basic unit of matter and that make up the objects which can be visible and touched every day, the amount of matter in an object can be determined by its mass.
A physical property of matter is an independent of its chemical composition. Density, color, hardness, melting and boiling points, and electrical conductivity are the examples.
Some characteristics like density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature are some properties of matter.
