A neutral isotope has 49 neutrons and 36 electrons. Identify the element symbol of this isotope and determine the mass number an

Marta_Voda [28]

Explanation:

In an atom , the relation between the subatomic particles of the atom are given as follows -

For a neutral atom ,

Atomic number = number of protons = number of electrons ,

Mass number = number of protons + number of neutrons,

Hence , from the given information of the question,

number of neutrons = 49 ,

number of electrons = 36 ,

Hence , by using the above relation,

Atomic number = 36

number of protons = 36

Since ,

Mass number = number of protons + number of neutrons

Mass number = 36 + 49 = 85 .

By taking the help of periodic table , as atomic number = 36 ,

The elements is Krypton ( Kr )

Kr ⁸⁵₃₆

When you convert feet to inches, how do you decide which portion of the conversion factor should be in the numerator and which i

Inessa05 [86]

Answer : The conversion used is, $1\text{ feet}=12\text{ inches}$

Explanation :

The conversion used :

$1\text{ feet}=12\text{ inches}$

For example : To convert 10 feet into inches.

$1\text{ feet}=12\text{ inches}$

$10\text{ feet}=10\text{ feet}\times \frac{12\text{ inches}}{1\text{ feet}}$

$=120\text{ inches}$

From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be, $\frac{12\text{ inches}}{1\text{ feet}}$
