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.
What else can I help you with?
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
In modern periodic table the elements are designed on ascending seris of 1. atomic mass 2. mass number 3. atomic number 4. electromic configuration?
In the modern periodic table, elements are arranged in ascending order of atomic number. This is because the properties of elements are primarily determined by the number of protons in the nucleus, which is the atomic number. The periodic table is organized in a way that elements with similar chemical properties are grouped together in columns (groups) and elements with increasing atomic number are arranged in rows (periods). Mass number, atomic mass, and electron configuration are related properties but are not used as the primary basis for organizing elements in the periodic table.
This element has an atomic number lower than that of aluminum and one less valence election than the group 16 elements?
The element with an atomic number lower than aluminum is silicon, which has an atomic number of 14. Group 16 elements, like oxygen and sulfur, have 6 valence electrons, whereas silicon has 4 valence electrons.
An atom has a mass number of 9 and 5 neutrons What is its atomic number?
To find the atomic number, subtract the number of neutrons (5) from the mass number (9). The atomic number of the atom in question is 4.
What four things does a periodic table tell us?
The periodic table tells us:The elements atomic massThe elements atomic numberIf the element is a gas, metal, etc.How many protons, electrons and neutrons an element hasThe name of the elementWhich elements could have similar properties (nearby in the chart)(Oops that was already six things (but some of them depend on the others)
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.
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.

What is the atomic number for berylliam?
The atomic number for beryllium is 4.
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.
What is the atomic number of Berylium?
The atomic number of Beryllium is 4.
What is the atomic number and number of valence electrons for each nucleic acid elements?
For carbon (C): Atomic number 6, 4 valence electrons. For hydrogen (H): Atomic number 1, 1 valence electron. For nitrogen (N): Atomic number 7, 5 valence electrons. For oxygen (O): Atomic number 8, 6 valence electrons. For phosphorus (P): Atomic number 15, 5 valence electrons.
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 is the atomic number of the element with the symbol Be?
The atomic number of the element with the symbol Be (Beryllium) is 4.
This element has an atomic number lower than that of aluminum and one less valence election than the group 16 elements?
The element with an atomic number lower than aluminum is silicon, which has an atomic number of 14. Group 16 elements, like oxygen and sulfur, have 6 valence electrons, whereas silicon has 4 valence electrons.
What is period 4 lowest mass?
In the periodic table, period 4 elements have atomic numbers ranging from 19 (potassium) to 36 (krypton). The element with the lowest mass in period 4 is potassium (K), which has an atomic number of 19 and an atomic weight of approximately 39.1 atomic mass units.
