Which element that has 4 proton and 5 neutrons?
Berylium
What is the metalloid element with the fewest number of protons?
If you look at the periodic table, the atomic number denotes the number of protons in the element. For example, the first element on the table is hydrogen, and it has one proton (the fewest). Element number two is helium, and it has two protons, etc.
How would you describe the isotopes of hydrogen?
Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Protium is the most abundant and consists of one proton and one electron. Deuterium contains one proton, one neutron, and one electron. Tritium has one proton, two neutrons, and one electron.
What gaseous element has 5 valence electrons and fewer neutrons than sodium?
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.
The element boron how many protons and neutrons does it have?
Boron has 5 neutrons and 5 protons for its most common isotope
What gaseous element has 5 element electrons and fewer neutrons than sodium?
The element with 5 fewer electrons than sodium is not a gaseous element!
What element is in period 5 and is a transition element and has 51 neutrons?
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).
How many protons neutrons and electrons are in Bi?
Five proton and electrons, 6 neutrons. This because this is the atomic number of boron, which states how many protons and electron in the element. For neutrons you must subtract the atomic number (5 in this case) from the rounded. average atomic mass.
What is boron atomic mass?
Atomic Mass Number Of Boron.The Atomic Mass Number Of Boron Is 10.81 Its Atomic number is 5. It has 5 p neutrons , 6 neutrons and 5 electrons. Its valency is 3. it has 3 valence electrons.
What element is period 5 element 51 neutrons?
An element with an atomic number of 51 and 51 neutrons is antimony (Sb). Antimony has an atomic mass of approximately 102, which is the sum of its protons (51) and neutrons (51). In the context of the periodic table, it is located in period 5 and group 15.
What is the identity of an element with 5 protons 7 neutrons and 5 electrons?
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
