atomic number of elements are the number of protons
in neutral atoms number of protons are equal to number of electrons
electrons are responsible for the chemical bonding in atoms
bonding depends on the number of valence electrons in the outermost shells.
atom A with 11 protons have 11 electrons, electronic configuration is - 2,8,1
atom B with 17 protons have 17 electrons, electron configuration is - 2,8,7
A has 1 valence electron and B has 7 valence electrons
therefore A prefers to give away its one valence electron and have a complete outer shell and B prefers to take in that one electron from A to become a complete octet.
The type of bond is an ionic bond formed by the transfer of electrons from one species to another species
answer is ionic
The number of protons and neutrons in the nucleus.
Answer: well our digestive system is very sensitive so when you chug a drink to fast or you eat way to fast, it causes your diaprgam to go in and out fast flexing, so it’s causes us to hiccup.
it is also the same for as when we breath

Answer:
Option (C)
Explanation:
In the field of astronomy, the redshift is defined as the shifting of the wavelength of light towards the red color of the spectrum. It describes about how the universe is expanding in every direction. The scientists have observed that the light in the universe emitted from distant objects such as the stars and galaxies is redshifted. This provides an example of Doppler's effect that is generally defined as the change in the wavelength of a wave that occurs when an observer moves relative to the source of the wave.
Hence, the correct answer is option (C).
Answer:
A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow. In a balanced chemical equation, the numbers of atoms of each element and the total charge are the same on both sides of the equation.
