Visualizing the Origin of Elements

Most of us are familiar with the periodic table of elements from high school chemistry. We learned about atoms, and how elements combine to form chemical compounds. But perhaps a lesser-known aspect is where these elements actually come from.

Today’s periodic table showing the origin of elements comes to us from Reddit user u/only_home, inspired by an earlier version created by astronomer Jennifer Johnson. It should be noted that elements with multiple sources are shaded proportionally to reflect the amount of said element produced from each source.

Let’s dive into the eight origin stories in more detail.

The Big Bang
The universe began as a hot, dense region of radiant energy about 14 billion years ago. It cooled and expanded immediately after formation, creating the lightest and most plentiful elements: hydrogen and helium. This process also created trace amounts of lithium.

Low Mass Stars

Low Mass Star
At the beginning of their lives, all stars create energy by fusing hydrogen atoms to form helium. Once the hydrogen is depleted, stars fuse helium into carbon and expand to become red giants.

From this point on, the journey of a low and a high mass star differs. Low mass stars reach a temperature of roughly one million kelvin and continue to heat up. Outer layers of helium and hydrogen expand around the carbon core until they can no longer be contained by gravity. These gas layers, known as a planetary nebula, are ejected into space. It is thought that a low mass star’s death creates many heavy elements such as lead.

Exploding White Dwarfs
In the wake of this planetary nebula expulsion, a carbon core known as a “white dwarf” remains with a temperature of about 100,000 kelvin. In many cases, a white dwarf will simply fade away.

Sometimes, however, white dwarfs gain enough mass from a nearby companion star to become unstable and explode in a Type 1a supernova. This explosion likely creates heavier elements such as iron, nickel, and manganese.

Exploding Massive Stars

High Mass Star
Massive stars evolve faster and generate much more heat. In addition to forming carbon, they also create layers of oxygen, nitrogen, and iron. When the core contains only iron, which is stable and compact, fusion ceases and gravitational collapse occurs. The star reaches a temperature of over several billion kelvin—resulting in a supernova explosion. Astronomers speculate that a variety of elements, including arsenic and rubidium, are formed during such explosions.

Exploding Neutron Stars
When a supernova occurs, the star’s core collapses, crushing protons and neutrons together into neutrons. If the mass of a collapsing star is low enough—about four to eight times that of the sun—a neutron star is formed. In 2017, it was discovered that when these dense neutron stars collide, they create heavier elements such as gold and platinum.

Cosmic Ray Spallation
The shockwaves from supernova explosions send cosmic rays, or high energy atoms/subatomic particles, flying through space. When these cosmic rays hit another atom at nearly the speed of light, they break apart and form a new element. The elements of lithium, beryllium, and boron are products of this process.

Nuclear Decay
Supernova explosions also create very heavy elements with unstable nuclei. Over time, these nuclei eject a neutron or proton, or a neutron decays into a proton and electron. This process is known as radioactive decay and often creates lighter, more stable elements such as radium and francium.

Not Naturally Occurring
There are currently 26 elements on the periodic table that are not naturally occurring; instead, these are all created synthetically in a laboratory using nuclear reactors and particle accelerators. For example, plutonium can be created when fast-moving neutrons collide with a common uranium isotope in a nuclear reactor.

Discoveries Yet to be Made

There is still some uncertainty as to where elements with a middle-range atomic number—neither heavy nor light—come from. As scientific breakthroughs emerge, we will continue to learn more about the elements that make up the mass of our solar system.

Mapped: The Income a Family Needs to Live Comfortably in Every U.S. State

Families in expensive states require over $270,000 annually to live comfortably.



A map showing the income that two working adults with two children need to live comfortably in each U.S. state.

The Income a Family Needs to Live Comfortably in Every U.S. State

Families in the top five most expensive U.S. states require an annual income exceeding $270,000 to live comfortably.

This visualization illustrates the income necessary for two working adults with two children to maintain a comfortable lifestyle in each state.

“Comfortable” is defined as the income needed to cover a 50/30/20 budget, with 50% allocated to necessities like housing and utilities, 30% to discretionary spending, and 20% to savings or investments.

The calculations for family income needed in each state were done by SmartAsset, using the cost of necessities sourced from the MIT Living Wage Calculator, last updated on Feb. 14, 2024.

Massachusetts Tops the List

Massachusetts is the most expensive state to live comfortably in, requiring a total family income of about $301,184. Hawaii ($294,611) comes in second, followed by Connecticut ($279,885).

Housing is one main reason Massachusetts is an expensive state to live in, particularly in the Boston area. In addition, the state also has a high cost of living, including expenses such as healthcare and utilities.

Meanwhile, Mississippi is the least expensive state for a family to live comfortably, requiring $177,798 per year. Arkansas ($180,794) comes in second, followed by West Virginia ($189,363). In common, all these states share low prices of housing.
