How many neutrons would there be if An atom of gadolinium has an atomic number of 64 and a mass number of 155?
91
Is the symbol for an atom with 107 protons and 155 Neutrons 107 155 BH?
262107BHJust imagine the 262 is directly above the 107, the upper number is the atomic mass number which is the sum of the number of protons and neutrons while the lower number is the atomic number which is just the number of protons.
How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
Mendelevium -256 and mendelevium-258 what is the difference between the nuclei of these two isotopes?
Mendelevium 256 has 155 neutrons and mendelevium 258 has 157 neutrons.
How many protons electrons and neutrons are in Bohrium?
# of protons:107 # of electrons:107 # of neutron:155
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.

What is the element mendelevium atomic structure?
The atom of the isotope Md-256 has 101 protons, 101 electrons and 155 neutrons.

How many neutrons are in europium?
europium's atomic number is 63, it's mass (in amu's [atomic mass units]) is 152, rounded. the atomic number = the number of protons, so europium has 63 protons. the number of protons = the number of electrons, so there are 63 electrons in a europium atom. the mass= protons + neutrons, therefore neutrons = mass - protons. this would be 152 - 63 = 89 there are 89 neutrons in a europium atom. p+: 63 n: 89 e-: 63 hope i helped! ^.^
How many atoms of sulfer are present in 155 grams of sulfer?
The atomic weight of sulfur is about 32.066. Therefore, 155 grams of sulfur contains 155/32.066 or about 4.83 gram atomic masses of sulfur to the justified number of significant digits. Each such gram atomic mass contains Avogadro's number of atoms, for a total of 4.83 X 6.022 X 1023 or 2.91 X 1024 atoms.
What is my mass in kilograms if I weigh 155 pounds?
155 pounds = 70.3kg
How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
Mendelevium -256 and mendelevium-258 what is the difference between the nuclei of these two isotopes?
Mendelevium 256 has 155 neutrons and mendelevium 258 has 157 neutrons.
How many protons electrons and neutrons are in Bohrium?
# of protons:107 # of electrons:107 # of neutron:155
What is the atom of mendelevium?
The atom of the isotope Md-256 has 101 protons, 101 electrons and 155 neutrons.
What is the density if a car has a volume of 125mL and a mass of 155g?
Density = mass/volume = 155/125 = 1.24 g/cm3.
