What is the number of protons in a nucleus of an element?
In chemistry, we use quite a bit. On the periodic table you can decide whether it's a metal, metalloid or nonmetal (excluding transition metals). You can also gather information on...

An element has an atomic number of 76. What is the number of protons and electrons in a neutral atom of the element?
By definition, the , $Z$, is the number of protons, positively charged, massive, nuclear particles, contained in the nucleus. $Z$ specifies the identity of the atom. And if there...

Element X has two isotopes. X-15 has 7 protons and 8 neutrons. What is the atomic number and mass number of the second isotope, which has 10 neutrons in its nucleus?
The most important thing to keep in mind here is that are atoms that have the same number of protons inside their nuclei. In other words, an isotope...

$"Atom W has 9 protons and 9 neutrons, Atom X has 8 protons and 9"$ $"neutrons. Atom Y has 9 protons, and 9 neutrons. Atom Z has 10 protons"$
$"and 10 neutrons."$
What are the isotopes?
And $Z$ defines the identity of the element: $Z=1,H;Z=2,He;..........Z=6,C;........Z=37, Ru...........$ You don't have to remember these numbers, because a Periodic Table will be supplied to you in every test of...

All the atoms of a particle element have an equal number of protons and neutrons (Z=N). Which one is true?
A) The atomic weight must be a whole number.
B) The mass number must be exactly twice the atomic number for each atom.
The answer is B) The must be exactly twice the for each atom. The number of protons is the atomic number of an element. The mass number is the sum...

An isotope of U-235 has 92 protons in its nucleus. How many neutrons are there in the nucleus of a U-238 isotope?
We are given that $Z_"uranium"=92$...because this is the number of protons, massive, positively charged particles present ion the uranium nucleus. $Z="the atomic number"$ and it DEFINES the identity of the...

A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 g of element C. What is the percent (by mass) of each element?
$%A$ $=$ $(34.5*g)/(34.5*g+18.2*g+2.6*g)xx100%=62.3%$ $%B$ $=$ $(18.2*g)/(34.5*g+18.2*g+2.6*g)xx100%=33.0%$ $%C$ $=$ $(2.6*g)/(34.5*g+18.2*g+2.6*g)xx100%=4.70%$ That is $%" element"$ $=$ $"Mass of element"/"Mass of compound"xx100%$ $"Mass of compound"$ is clearly the SUM of the constituent ....
