Question

explain
(I) atomic
(ii) mass
(iii) istopes
(iv) Isobars
(v) name the istopes of hydrogen

​

Answer 1

Answer:

1. Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
2. Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).
3. one of two or more forms of a chemical element that have different physical characteristics but the same chemical characteristics
4. Isobars are elemnts which have different atomic numbers but the same mass number. They are different chemical elements.

Answer 2

Answer:

i) atom= Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry. shell atomic model.

ii) mass= Mass is the measure of object's inertia, more the mass more the inertia. It is a property of material , so it does not change with place. SI unit is 'kg'. It is a scalar quantity.

iii) isotopes= Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

iv) isobars=Isobars are atoms of different elements with the same mass number but different atomic numbers.

v) example= deuterium, and tritium. 

vi) atomic mass= The atomic mass is defined as the mass of 1/12 of C12
