Which of the following atoms would be expected to form positive ions in binary ionic compounds: Br, Ca, Na, N, F, Al, Sn, S, Cd? A. Ca, Na, Al, Sn, Cd
B. Br, N, F, S
C. N, Br, Cd, Na, Al

A

Explanation:

Hello,

Binary ionic compounds are those compounds that consist of two elements and usually one has a positive ion while the other one carries a negative ion and they both combine together to form a compound.

In the options above, option A is the right answer because it has a combination of positive ions.

For ionic compounds to form, a strong electropositive element must combine with a strong electronegative element.

Most metals are usually electropositive and carry a positive ion and non metals tends to carry negative ions.

Br = non metal = negative ion

Ca = metal = positive ion

Na = metal = positive ion

N = non metal = negative ion

F = non metal = negative ion

Al = metal = positive ion

Sn = metal = positive ions

S = non metal = negative ion

Cd = metal = positive ion

Option A has a combination of all the positive ions here.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
