Which element symbol has 51 neutrons and is on period 5?
Sb Antimony
Which element has 6 protons 5 neutrons and 8 electrons?
The isotope boron-11 has 5 protons and 6 neutrons, but also 5 electrons not 8.
What is the atomic number of an atom that has a mass of 9 and 5 neutrons?
The mass is protons + neutrons. So, if the mass is 9 and it has 5 neutrons, then there must be FOUR (4) protons. This would be the element beryllium (Be).
Which element has 5 electrons 5 protons and 5 neutrons?
boron10 would be the isotope that matches these descriptions
What element has an atomic mass of 8 and 8 neutrons?
the element that has 8 neutrons is Oxygen
What element has 5 proton 5electrons and 5 neutrons?
Boron
What has 5 valence electrons and 16 neutrons?
The element is sulphur. It has 5 valence electrons and 16 neutrons.
The element boron how many protons and neutrons does it have?
Boron has 5 neutrons and 5 protons for its most common isotope
Which element that has 4 proton and 5 neutrons?
Berylium
What element has 5 neutrons 4 protons?
Beryllium
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 is the name of the element of period 5 transition element 51 neutrons?
It's Zirconium.
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).
Which element symbol has 51 neutrons and is on period 5?
Sb Antimony
What element has 4 electrons 5 protons and 4 neutrons?
Be- Beryllium
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.
Isotopes of an element have a different number of?
neutrons
