Fill in the missing information:
Neko [114]

Answer: 1. Complete Nuclear Symbol : _{22}^{48}{Ti^{4+}}

2. Atomic number : 22

3. Mass number : 48  

4. Charge : 4 +

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neelectrons. utrons and number of protons.

Given : no of protons = 22 , thus atomic number = 22

Mass number =  number of neutrons + number of protons

Mass number =  26 + 22 = 48

Also for a neutral atom , the number of protons is equal to the number of electrons. But here electrons are 4 less than protons, which means the atom has lost 4 electrons and thus will have a charge of 4+.

The atomic number is specific to an element, and the element with atomic number 22 is Titanium (Ti). The representation is _{22}^{48}{Ti^{4+}}

Distinguish between mass and weight
yKpoI14uk [10]

Answer:

There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
