What is the role of neutrons in the nucleus of an atom?
zhenek [66]
Neutrons keep the Protons "in check", meaning Protons hold a very strong repulsive positive charge. The Neutrons counteract the repulsive force within a small space to keep the Nucleus stable.

I hope this helps! :)

ankoles [38]

There are some exceptions to the rule organisms such as a protist called a  euglena can be both heterotrophic and autotrophic. This is a true statement.

Explanation:

  • Euglena is a large genus of unicellular protists: they have both plant and animal characteristics
  • Photoautotrophs include protists that have chloroplasts, such as Spirogyra. Heterotrophs get their energy by consuming other organisms. Other protists can get their energy both from photosynthesis and from external energy sources
  • All live in water and move by means of a flag ellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants
  • Euglena is photosynthetic in the presence of sunlight i.e autotrophic, when deprived of sunlight they behave like heterotrophs by predating on other smaller organisms.
  • Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. They can also take nourishment heterotrophically, like animals.

Rank the elements in each of the following sets in order of increasing IE₁:
zavuch27 [327]

Explanation:

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Therefore, ionization energy increases along a period.

But when we move from top to bottom in a group then there occurs an increase in size of the atoms. Hence, ionization energy decreases along a group.

(a)  As Sb, Sn and I are all period 5 elements. Hence, these elements are arranged in order of increasing IE_{1} as follows.

                             Sn < Sb < I

(b)  As Sr, Ca, and Ba are all elements of group 2a. Hence, these elements are arranged in order of increasing IE_{1} as follows.

                            Ba < Sr < Ca
