Atom A has six protons , five neutrons and five electrons. Atom B five protons , six neutrons, and five electrons . Are atoms A and B of the same element ? 1. no, because they do not have the same number of protons

2. no, because they do not have the same number of neutrons

3. yes , because they have the same number of electrons

4. yes , because both have 16 protons , neutrons, and electrons combined

no, because they do not have the same number of protons

Explanation:

No of protons represents atomic number which decides the characteristics of an atom . Two atoms having same number of protons but different number of neutrons are same element . They differ only in some physical characteristics . They are called isotopes . In respect of chemical properties they are same .  In a neutral element number of protons and number of electrons are same . But in some case number of electrons may differ . In that case they form ions of the element . In positive ion , number of electrons is shorter than number of protons .

In the present case , atom A and atom B differ in respect of number of protons so they represent different element .

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
