When sunlight excites electrons in chlorophyll how do electrons change?

As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.


Why do elements produce light?

Elements produce light when their electrons move from higher to lower energy levels within the atom. This movement releases energy in the form of photons, which are particles of light. Different elements emit light at specific wavelengths, creating the characteristic colors of flames or glowing objects.


How does the numbers of electrons change across a period of elements?

The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).


Frequency of specific elements always the same?

In a stable isotope, the frequency of specific elements remains consistent under normal conditions due to the presence of a constant number of protons, electrons, and neutrons within the atoms. This stability ensures that the relative abundance of isotopes of an element does not change without external influences.


Does strontium lose or gain electrons in a chemical change?

Strontium typically loses electrons in a chemical change because it belongs to Group 2 of the periodic table, which contains elements that tend to lose two electrons to achieve a stable electron configuration.


What are two ways in which atoms of different elements are different from one another?

The number of protons, which determines the element's identity, varies between atoms of different elements. The arrangement of electrons in an atom, specifically the number of electrons in the outermost shell, differs among elements.


When moving down a group ( family) in the periodic table the number of valence electrons?

When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.


How does the number of valence electrons for element change across a period?

The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).


Are all the elements made up of the same type of atom?

All elements are made up of the same type of atom. The element changes when the number of protons and electrons change.


How do the parts of an atom combine to form compounds and mixtures?

It's not the atoms that change, it is the molecules... In short, the molecules(elements) can share, give, or take electrons from other molecules(elements).
