What two atoms have 20 electrons combined?
Two atoms that have a total of 20 electrons combined could be calcium (Ca) and potassium (K), as calcium has 20 electrons and potassium has 19 electrons. Alternatively, you could have two atoms of calcium, which would also sum up to 20 electrons. Another combination could be a calcium atom (20 electrons) and an oxygen atom (8 electrons) if we consider a different arrangement, but that would exceed the total.
Is potassium benzoate ionic or covalent?
ionic because it contains a metal and nonmetals.
Electron arrangement of chlorine?
Chlorines electron configuration can be described in a few different ways - it also depends on whether you are talking about chlorine gas or chlorine the atom. For the atom - chlorine has 17 electrons. Simply describes the electron arrange could be called 2, 8, 7 (where the number represents the # of electrons in each shell. From the more advanced atomic orbital theory - chlorines electron configuration could be notated as such: 1s2 2s2 2p6 3s2 3p5 (where the last number in each is superscript). For chlorine gas, the electron configuration is described using molecular orbital theory (university level) as such: non-valence electrons are ignored - since they are too far separated to combine their wavefunctions meaningfully - so we only consider valence electrons (3rd shell ie 3s and 3p in this case) σ3s2 σ3s*2 σ3p2 π3p4 π3p*4
Can you consider Be- Cl a polar bond?
Yes, a Be-Cl bond can be considered polar. Beryllium (Be) is less electronegative than chlorine (Cl), leading to an unequal sharing of electrons and the formation of a polar covalent bond.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
Can you consider zonrox as chlorine?
Zonrox is a brand of bleach that contains sodium hypochlorite, which is a form of chlorine. It is used for its disinfecting and whitening properties, similar to chlorine bleach. However, it is important to note that other types of chlorine, such as chlorine gas, are more commonly associated with pool sanitation and water treatment.
Is sodium and chlorine close together on the pereodic table?
Sodium is at the extreme left and chlorine is in the next-to-rightmost cell of period 3. Most would not consider that close.
Is potassium is the most easily reduced metal?
Technically, Francium would be the most easily reduced metal, however most people don't consider it to due its radioactivity. Next up though is Cesium. Rubidium is more easily reduced then potassium, and cesium is more easily reduced then rubidium.
What are the top features to consider when choosing the best aluminum wheelset for your bike?
When choosing the best aluminum wheelset for your bike, consider the following top features: weight, durability, rim width, hub quality, and compatibility with your bike's brakes and drivetrain.
How many grams of aluminum hydroxide are obtained from 17.2 grams of aluminum sulfide?
To determine the grams of aluminum hydroxide obtained from 17.2 grams of aluminum sulfide, we need to consider the stoichiometry of the reaction between aluminum sulfide and water to form aluminum hydroxide. Given the balanced chemical equation, we can calculate the molar mass of aluminum hydroxide and use it to convert the mass of aluminum sulfide to grams of aluminum hydroxide formed.
How many grams of aluminum oxide can be formed by the reaction of 1020g of aluminum with oxygen?
To determine the grams of aluminum oxide formed, we need to consider the balanced chemical equation for the reaction between aluminum and oxygen. The molar ratio between aluminum and aluminum oxide is 4:2. So, first calculate the moles of aluminum in 1020g, then use this to find the moles of aluminum oxide produced, and finally convert moles of aluminum oxide to grams.
How can you keep your chlorine levels up?
You can keep your chlorine levels up in your pool by regularly testing the water and adding chlorine as needed. Ensure the pH level is balanced first, as this affects the effectiveness of chlorine. Consider using stabilized chlorine products to prevent rapid dissipation from sunlight.
