B belongs to group 7 based on the valence shell electronic configuration of 7. To express the cost of capital in a single figure, one has to weigh its cost of debt and cost of equity proportionally, based on how much financing is acquired through each source. Element A belonging to Group 2 and period 4, is Calcium (Ca). A common request on this site is to convert grams to moles. Calcium Carbonate is an ionic compound and therefore we need to take into account ionic charges for each element. You can use the child and family benefits calculator to estimate how much you will get.Many companies generate capital from a combination of debt and equity (such as stock) financing. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

For families with two or more children eligible for the benefit, the reduction is 5.7% of the amount of adjusted family net income greater than $71,060.

For families with one child eligible for the benefit, the reduction is 3.2% of the amount of adjusted family net income greater than $71,060.

the charge on one Ca 2+ ion, so the proper ionic formula is CaCl 2. The process yielded the isotope californium-245 which has a half-life of 44 minutes.

They made it by firing helium nuclei (alpha particles) at curium-242. Classified as an alkaline earth metal, Calcium is a solid at room temperature. Californium was first made in 1950 at Berkeley, California, by a team consisting of Stanley Thompson, Kenneth Street Jr., Albert Ghiorso, and Glenn Seaborg. Give the name and formula of the compound firmed from the following elements: a).

Calcium being a metal of group II forms a divalent cation, Ca2+. So far, we have discussed elements and compounds that are electrically neutral. Calcium is a chemical element with symbol Ca and atomic number 20. The benefit starts being reduced when the adjusted family net income is greater than $71,060. Calcium chloride is made up of two elements i.e., calcium and chlorine. Your CDB payments are calculated using the following information:Įvery July, your CDB payments are recalculated based on your AFNI from the previous year.įor example, July 2022 to June 2023 payments are based on your income from your 2021 tax return and July 2021 to June 2022 payments are based on your income from your 2020 tax return.įor the period of July 2022 to June 2023, you could get up to $2,985 ($248.75 per month) for each child who is eligible for the DTC. For general questions related to the CDB, call 1-80 or for information related to the DTC, call 1-80.
