Answer:

1.How many isotopes does Hydrogen have? three isotopes

2.Do they have the same number of protons/atomic number?The number of protons in an atom is called its atomic number (Z).

3.Do they have the same number of neutrons?The number of neutrons can be different, even in atoms of the same element.

4.Which has the smallest mass number?Atom

5.Which has the largest mass number?Oganesson

Step-by-step explanation:

1.three isotopes

three isotopesThere are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium. How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons.

2.The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

3.The number of neutrons can be different, even in atoms of the same element. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.

4.atom

atomatom: The smallest possible amount of matter which still retains its identity as a chemical element, consisting of a nucleus surrounded by electrons. proton: Positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element. It weighs 1 amu.

5.Oganesson

OganessonOganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.
