Question

atom contain the same number of protons
as neutron true or false ​

Answer 1

Answer:

proton and neutrons have approximately same mass. However one proton is about 1,835 times more massive than electron.Atoms always have same number of proton and electron,and the number of proton and neutron is usually same as well.Adding proton to an atom makes a new element,while adding neutron makes an isotope of that atom.

Answer 2

Answer:

False

True in most cases, but not in all.

Explanation:

An atom is neutral, means it has no charge or we say it has positive and negative charge in equal ratio.

In atom, negative charged in contained in electrons, whereas, positive charged in contained in protons.

So, be nuetrally charged,

→ -ve charge = + charge

→ charge on e- = charge on p+

→ no. of e- = no. of p+

This is a must condition for an atom. Here, there is no signifincance of neutrons.

Neither no. of p+ = no. of neu.

Atom contains same number of e- & p+, to attain 0 charge, neutron has no work in this.

So, number of protons and neutron may or may not be equal.

As it is not same in all atoms.

It must be false.
