Answer from: anaislewis457

The number of neutrons does an atom of tungsten (W) has is

110 neutrons

Explanation

Atomic mass of tungsten = total number of protons and neutrons in a nucleus of tungsten.

Therefore the neutrons of tungsten = Atomic mass of tungsten- protons of tungsten

Atomic mass of tungsten = 183.84

Tungsten protons = 74

Tungsten neutron is therefore= 183.84 - 74 = 109.84 which is approximate

110 neutrons

Answer from: jadenp23

The number of neutrons in the nucleus of Tungsten is 110.

Nucleus of all atoms are composed of protons and neutrons. The atom contains electrons equal in number to the protons present inside the nucleus.The entire mass of the atom is contained in the nucleus. The total mass of the electrons is negligible when compared to the total mass of the protons and the neutrons.

Protons have an atomic mass mp of 1.007277 u, while that of neutrons mn is 1.008665 u and of me electron is 0.0005486 u.

Tungsten has 74 protons and 74 electrons.

Calculate the total mass m of 72 protons and 72 electrons.

$m= 72 ( m_p +m_e )\\=(72)(1.007277 u+0.0005486 u)\\ = 72.5634 u$

Calculate the total mass of the neutrons by subtracting the mass m from the total mass of the nucleus M.

$M_n = M - m\\ = (183.84 u)-(72.5634 u)\\ = 111.2766u$

Divide the total mass of the neutrons by the mass of one neutron to obtain the number of neutrons.

$n =\frac{M_n}{m_n}\\ =\frac{111.2766u}{1.008665u} \\ =110.3$

Thus the number of neutrons in Tungsten atom, rounded to the nearest whole number is 110.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
