Answer:
Selenium
Explanation:
One way to figure this out is to count the electrons and add them up.
2+2+6+2+6+2+10+4 = 34 electrons
A neutral atom has the same number of electrons and protons. Protons tell us the atomic number of an element. Element number 34 is Selenium.
Another way to figure it out is to look at just the highest "s" or "p" level of the electron configuration, and then see which element corresponds to that. This element has a 4s and a 4p, so I will look at 4p. The configuration is 4p4, so I will look at the 4th row of the periodic table (4p4) in the "p" block (4p4) and the 4th element in the "p" block (4p4). That's selenium :)
The cure for polio is an applied science. The vaccination as the cure of the disease uses applied science<span> that applies existing knowledge in science to develop practical technology or inventions like the vaccine. Answer to this problem is applied/</span>
Molar Mass of 1 molecule of methane(CH4) = 12 + 4 = 16g/mol
That is, 16g if CH4 contain 1 mole molecule of it
= 6.022×10²³ molecules of CH4 which consists of 1 mole of C atoms and 4 moles of H atoms.
=> 4 g of CH4 contains 1/4 × 6.022×10²³ molecules
= 1.5055×10²³ molecules of CH4
= 1.5055×10²³ C atoms and 6.022×10²³ H atoms
Note: the question should be how many atoms of hydrogen and carbon and not molecules.
Hope it helps…
The correct answer is 92. <span> uranium atom has 92 protons and 92 electrons. hope this helped, have an amazing day :)</span>
