Answer :
(1) The correct option is, It consists of positively charged protons and uncharged neutrons.
(2) The correct option is, a sodium atom loses an electron.
Explanation :
As we know that an atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
Atom : It is a smallest unit of matter which can not be further divide.
When the atoms have equal number of protons (which is positively charged) and electrons (which is negatively charged) then the atoms are electrically neutral.
When an atom gains or lose one or more electrons then it becomes an ion. The ion can be anion by gaining an electron and can be cation by losing an electron.
As per question, the neutral atom Na has equal number of protons and electrons i.e 11 but ion has unequal number of protons and electrons that means it has 11 number of protons and 10 number of electrons.
This means that, a sodium atom loses an electron during the formation of ion.
