Answer:
Plutonium and Uranium are elements that are found in the actinide series of the periodic table. They are different from each other in several properties as discussed in this article above. The main difference between Plutonium and Uranium is that Plutonium is highly radioactive whereas Uranium is weakly radioactive.
Answer:
Bromine (35) 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p⁵
Magnesium(12) 1s2 2s2 2p6 3s²
Selenium (34) 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p4
Explanation:
In the SPDF electronic configuration, the S orbital can accommodate maximum of 2 electrons,
The P orbital has maximum of 6 electrons
The D orbital has maximum of 10 electrons
The F orbital has maximum of 14 electrons
Bromine with atomic number 35 belongs to group seven(7) period four (4) it ground state electron configuration is 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p⁵
Magnesium with atomic number 12 belongs to group one, period two(2), it ground state electron configuration is 1s2 2s2 2p6 3s²
Selenium has atomic number of 34, it belongs to group six(6), period four(4) it electronic configuration is 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p4
5 moles.
think about the ratio of moles of iron oxide (Fe2O3) and iron (Fe) in that balanced chemical equation, which is 1:2, respectively. if there are 10 moles of Fe, you would divide that by 2 to get the number of moles of Fe2O3.
Answer:
Contributes to the membrane potential.
Explanation:
Sodium-potassium pump: In cellular physiology, a protein which is identified in many cells that helping in to maintain the higher concentration of potassium ions inside than that is in the surrounding medium and maintain the lower concentration of sodium ions inside than that of the surrounding medium.
This unbalanced charge transfer contributes in the separation of charge across the cell membrane. Sodium-potassium pump is known for important contributor to action potential which is produce by nerve cells.
A molecule of a compound is composed of at least two types of atoms.
Explanation:
A molecule is defined as when two or more atoms of an element combine together by the bonds by sharing the electrons as O^2 (oxygen molecule)
A compound is a molecule when two different types of atom joined by chemical bonds as covalent, ionic or coordinate bonds as NH^3 ( ammonia)
