Answer : The properties which would be the same among isotopes of the same element are Flammability and Color
Explanation :
Isotopes are the elements that have same number of electrons and protons but they differ in number of neutrons.
The chemical properties of an element are determined by its valence electrons and since isotope have same number of electrons, they have similar chemical properties.
But isotopes have different number of neutrons. Neutrons are the subatomic particles which are present in the nucleus. They are charge less particles and they have mass. Therefore when the elements have different number of neutrons, their atomic masses differ.
As a result, isotopes have different mass related physical properties.
Let us discuss the given properties now
1) Flammability : Flammability in simple words means the ability of the substance to catch fire or the ability to burn. This is mainly dependent on the reactivity which is in turn dependent on the number of electrons.
Since the isotopes have same number of electrons, they show similar flammability.
2) Density : Density is defined as mass per unit volume. This property involves mass and we know that isotopes have different masses. Therefore they have different densities too.
3) Melting point : Melting point is a physical property which is mainly dependent on the molecular weight of the substance. Since isotopes have different masses, they tend to show different melting points.
4) Color : The color of the element is mainly dependent on the arrangement of electrons around the nucleus. Isotopes have same number of electrons which means the arrangement would also be the same. Therefore the isotopes of the same element do not show different colors.
The properties which would be same among isotopes of the same element are
1) Flammability
4) Color
Answer: D. Color

So much for expert verified^^ smh
gold is more dense than wood? hope its right!
Answer:gold is more dense than wood wood has like air bubbles in it which makes it float and gold is solid with no bubbles
Explanation:
We have that for the Question "how many atoms are in Na2CrO4" it can be said that The total number of atoms is
From the question we are told
how many atoms are in Na2CrO4
Generally
In identifying the atoms are in Na2CrO4 we must first look closely at the compound Na2CrO4
We have
Na=1
Cr=2
O=4
Therefore
The total number of atoms is
X=1+2+4
X=7 atoms

Answer:
6.0 x 105
Explanation:
Answer:6.0 x l05
Explanation:
Liquid reactant A: 10 g
Liquid reactant B: 17 g
Beaker+Solid product: 32 g
What is the mass of the beaker?
a. 5 g
b. 10 g
c. 15 g
d. 17 g
e. 32 g
This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)
10+17=17
Total amount is 32
32-17=15
15 is you mass
Hope this Helps
Its 5g i took the quick check
