The element with an atomic number of 4 is helium. Helium is a colorless odorless tasteless non-toxic inert monatomic gas. It is the second lightest element and the second most abundant element in the universe. Helium is most commonly found on Earth as a by-product of natural gas production. It is used in a variety of applications including:
- Cryogenics
- Arc welding
- Pressurizing liquid-fueled rockets
- Gas lasers
- Breathing gas for divers and astronauts
Helium is also used as a coolant in nuclear reactors and MRI machines. It is also used to detect leaks in vacuum systems and pressurized gas systems.

Are elements in a period arranged alphabetically?
Yes, the periodic table is arranged in order of increasing atomic number. An element's atomic number is a count of its number of protons. If you arrange the elements in this way, certain properties become recurring, or periodic, which is why it's called that.
In modern periodic table the elements are designed on ascending seris of 1. atomic mass 2. mass number 3. atomic number 4. electromic configuration?
Atomic number = number of protons.
How many protons does an atomic number of four have?
Four.
Does group 4 on the periodic table elements have four valence electrons?
All elements in the 4th period (elements with atomic number 19 to 36) have four energy levels.
What is the periodic symbol of the element cobalt?
Co
If the atomic number of 4 different elements is 102 what does itmean?
Atomic number is unique. It cannot be same for different elements.
What are the 4 things that the elements in the p-block contains?
It contains the symbols, atomic number, atomic name and the real name of the elements.

What are the group number and period of the elements in the periodic table if it has an atomic number of 40?
Zirconium(Zr) has an atomic number of 40. It is in Group 4 and Period 5.
In modern periodic table the elements are designed on ascending seris of 1. atomic mass 2. mass number 3. atomic number 4. electromic configuration?
Atomic number = number of protons.
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
What element has a smaller atomic mass than element 5?
If "element 5" in this question means the element with atomic number 5, then all of the elements with atomic numbers 1 through 4 have smaller atomic masses. These elements are hydrogen, helium, lithium, and beryllium.
How many protons does an atomic number of four have?
Four.
Does group 4 on the periodic table elements have four valence electrons?
All elements in the 4th period (elements with atomic number 19 to 36) have four energy levels.
How many neutrons and electrons does berylluim?
neutrons in berylium are 5 because Atomic mass - 9 Atomic number - 4 number of neutrons = Atomic mass - Atomic number = 9 - 4 = 5 neutrons = = berylium is metal = no berylium is not a true metal most of its properties are similar to the non metals.....
Where is elements located?
Hafnium is a natural chemical element, rare, solid transition metal, atomic number 72, group 4 and period 6 in the table of elements.
What is the periodic symbol of the element cobalt?
Co
