The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:

   b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.

The extension to atoms with more than one electron in the last shell the model results are not completely correct.

The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.

In the case presented of Neon, its electronic configuration is

    1s² 2s² 2p⁶

Let's examine the different claims:

a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.

b) True. The protons are in the nucleus and the electrons are in circular orbits.

c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.

c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .

In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:

  b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

Answer:

whatttttttttttttttttttttttt

Answer:

Breaking glass - chemical change

popsicle - physical

milk - chemical

bread - physical

roasting - chemical

egg - chemical

fireworks - chemical

mixing something with water - chemical

popcorn - chemical

colouring hair - physical

melting chocolate - physical

crumpled paper - physical

rusted nails - chemical

crushed can - physical

cooked egg - chemical

bending metal - physical

melting ice - physical

bleaching clothes - chemical

If u want to differentiate between chemcial and physical change u need to remember this-

physical change - no new substance is formed (Even for melting of ice it's still water) and it can be reversible, except for some cases like tearing of paper

chemical change - a new substance is formed

Explanation:

gas and liquid flow around and take the shape of their containers because the molecules are more spread apart

Answer:

A solvent is simply a substance that can dissolve other molecules and compounds, which are known as solutes. ... Because of its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.

Answer:

the bond that forms between carbon and oxygen to create carbon dioxide

A polar covalent bond

Answer:

pressure doubles

Explanation:

they are inversly preportional

Answer:

Liquid water is held together by hydrogen bonds. Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds.Water will not do this so the oil is forced to stay separate from the water.

Oil are the lipid molecule do not Mix With Water Because of Polarity. Oil and water don’t mix as it  is made up of non-polar molecules while water molecules are polar.

Lipids are organic biomolecule made up of carbon, hydrogen and oxygen with some other elements like phosphorus and nitrogen may be present.

A fatty acid which is an organic acid having hydrogen and general formula R-COOH where R represents hydrogen or a group of carbon and hydrogen atoms, for example stearic, palmitic and oleic acids.

Glycerol is another component which is a thick sweetish liquid, soluble in water and  can react with a fatty acid. where one molecule of glycerol combines with three molecule is fatty acids by formation of a bond called ester, here ester is also known as triglyceride.

Answer:

chemical stability is important to consider in the comprehensive assessment of pharmaceutical properties, activity, and selectivity during drug discovery.

Answer:

In general, molecules are stable because all their constituent atoms have sufficient "valence" electrons-that is, electrons that participate in chemical bonding. Such electrons reside in the outer, or valence, "shell," which must fill up with the appropriate number of electrons for the bound atoms to be come stable.

Answer:

50,000,000 Hz

Explanation:

Rearrange the formula:

wave speed = frequency × wavelength → frequency = wave speed ÷ wavelength

wave speed = 300,000,000m/s

wavelength = 6m

Substitute in the values:

frequency = 300,000,000 ÷ 6

frequency = 50,000,000 Hz
