Enter a balanced nuclear equation for the production of lutetium-177, used in the treatment of some cancers, from the beta decay of ytterbium-177.

Explanation:

Beta-decay: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released is basically a electron with -1 charge and no mass.

General representation of an element is given as:  

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
