The stability of an isotope is based on its(1) number of neutrons, only
(2) number of protons, only
(3) ratio of neutrons to protons
(4) ratio of electrons to protons

Answers

Answer 1
Answer: Option 4. ratio of electrons to protons

Isotope that has atomic number of 82 is stable. An element that has an atomic number ∠82 more stable except Tc and Pm. Also there is the concept that isotopes consisting a combination of even-even,even-odd,odd-even, and odd-odd are all stable. Many isotopes with no magic numbers of nucleons are stable

Which atomic model proposed that electrons move in specific orbits around the nucleus of an atom

Answers

The atomic model that proposed that electrons move in specific orbits around the nucleus of an atom is the Bohr model, or the Rutheford-Bohr model, envisioned by Niels Bohr in 1913.

Calculate the density of a piece of bone with a mass of 3.8 grams and a volume of 2.0 cubic centimeters. 1.9 g/cm3 0.53 cm3/g 7.6 g /cm3

Answers

Answer: The density if the bone is 1.9g/cm^3.

Explanation:

Mass of the bone =  3.8 grams

Volume of the bone = 2.0 cm^3

Density is defined as mass present in per unit volume of the substance.

density=(Mass)/(Volume)=(3.8 g)/(2.0 cm^3)=1.9g/cm^3

The density if the bone is 1.9g/cm^3.

Answer:

1.9 g/cm

That's your answer!!

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) 2NH3(g) What occurs when the concentration of H2(g) is increased?

Answers

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) = 2NH3(g). When the concentration of the hydrogen gas is increased, the equilibrium will tend to go to the products or to the forward reaction. Therefore, more products are formed.
