Answer 2

Isobars have d) an equal mass number

• Isobars are defined as the elements with same mass number but different atomic number.
• Elements with same atomic number but different mass number are called isotopes. This indicates that these elements have same number of protons and electrons.
• Elements with same number of neutrons are called isotones.
• Atom is made up of minute constituent particles called proton, neutron and electron.
• Protons and electrons are responsible for charge on the atom. Protons are positively charged and electrons are negatively charged.
• Change in number of either of them, makes them ions which are reactive in nature.
• Neutrons are the neutrally charged particles.
