Answer: Na has a ground-state electronic configuration of 1s2 2s2 2p6 3s1. Removing the 3s electron leaves us with the noble gas configuration 1s2 so a sodium ion is Na+.
Explanation: I HOPE THAT HELPED!
The ground state electron configuration for sodium (Na) is 1s²2s²2p63s¹. The electron in the outermost shell (3s orbital) is the valence electron, with the rest being core electrons. It can be abbreviated as [Ne]3s¹.
The ground state electron configuration for sodium (Na), an alkali metal with atomic number 11, is 1s²2s²2p63s¹. This configuration includes one electron in the outermost shell, or 3s orbital, and the rest in the core electron shells. To abbreviate this, we look at the noble gas that matches the core configuration, in this case neon (Ne), and the configuration becomes [Ne]3s¹. The outermost electron, in the 3s orbital, is known as a valence electron, while the others are core electrons.

Answer:
The correct answer is CO2 diffuses passively out of the cell.
Explanation:
Carbon dioxide is one of the end product of cellular metabolism.CO2 is produced as waste material inside the body after cellular respiration.
Carbon dioxide is transported out from the body by passive diffusion process which helps the CO2 gas to move along the concentration gradient from high concentration region(body) to the low concentration region(atmosphere).
Thus CO2 ia being eliminated from our body.
Answer:
Science is based on fact.
Explanation:
b.Light bounces off surfaces.
c.Light travels in a curved path.
d.Light is made up of waves.
Answer : Option B) Light bounces off Surfaces.
Explanation : Zaccharias Janssen a scientist who was a spectacle maker, is considered to be the founder of a compound microscope; believed that the ray of light when focused on a reflecting surface bounces back. This was the main property of light which he discovered and which led him to a new innovation.
Diffusion is the process by which dissolved gases are exchanged between the blood and interstitial fluids.
The process by which dissolved gases are exchanged between the blood and interstitial fluids is called diffusion because molecules from high concentrated region moves to the place of lower concentrated region.
We know that diffusion is a process in which molecules from a region of higher concentration moves to the region having lower concentration so the gases exchanged between blood and interstitial fluid so we can conclude that diffusion is the process by which dissolved gases are exchanged between the blood and interstitial fluids.

Answer:The process by which dissolved gases are exchanged between the blood and interstitial fluids is called internal respiration.
Explanation:
Physiologically respiration is defined as the passing of oxygen the external environment into the cells within tissues, and the transport of carbon dioxide in the opposite direction.
Respiration is divided into three:
1.) The external respiration: this involves the inhalation of air and exhalation of used gases.
2.) The internal respiration: this is defined as a process of diffusing oxygen from the blood, into the interstitial fluid and into the cells
3.) Cellular respiration: this involves the conversion of food to energy. Its further divided into aerobic respiration, which is a cellular respiration that requires oxygen and anaerobic respiration which does not.
