Because the core of the sun is so hot, what heavier element is created when hydrogen atoms fuse together in the sun’s core?

Answer is: helium.

Nuclear reaction is in the inner core of the Sun and hydrogen is conveted into helium.

The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.

The Sun interior is divided into three regions: the inner core, the radiative zone and the convection zone.

Helium (symbol: He) is an element with atomic number 2 (2 protons) and mass number 4 (2 neutrons; n° = 4 - 2 = 2).

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
