Carrie is making a presentation on solar winds. Her notes of the steps that must occur for solar winds to form are below. 1. The stream of electrically charged particles collide with gas atoms, causing the latter to give off light. 2. The electrically charged particles flow outward in all directions as far as Saturn. 3. The stream of electrically charged particles flows outward from the corona. 4. The particles of the solar wind flow along lines of the magnetic field. Which shows the correct sequence in the formation of solar winds? 1, 2, 3, 4 2, 3, 4, 1 3, 2, 4, 1

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
