How many neutrons does the following nuclide have? 253/100 fm a. 253 b. 100 c. 153 d. none of these

Answer : The correct option is, (C) 153

Explanation :

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

or,

Number of neutrons = Mass number - Atomic number

As we are given that:

The given nuclide is,

'Fm' is the fermium element.

Mass number of 'Fm' = 253

Atomic number f 'Fm' = 100

Now we have to determine the number of neutrons.

Number of neutrons = Mass number - Atomic number

Number of neutrons = 253 - 100

Number of neutrons = 153

Therefore, the number of neutrons in the 'Fm' nuclide have 153.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
