Answer:
The air around you
Explanation:
Matter is defined as anything that has mass and occupy space. Matter may sometimes not be seen with naked eyes.
The decision we had to take on the answer is based on the fact that air has mass and does occupy space.
Air can be trapped in a container and its mass measured hence air is an example of matter.
Ionization energy is the energy required to lose an electron and form an ion. The stronger is the attraction of the atom and the electron the higher the ionization energy, and the weaker is the attraction of the atom and the electron the higher the ionization energy. This leads to a clear trend in the periodic table. Given that the larger the atom the weaker the attraction of the atom to the valence electrons, the easier they will be released, and the lower the ionization energy. This is, as you go downward in a group, the ionization energy decreases. So, the element at the top of the group will exhibit the largest ionization energy. <span>Therefore, the answer is that of the four elements of group 7A, fluorine will have the largest first ionization energy.</span>
The vertical component of velocity is zero
The periodic table lists all the elements, with information about their atomic weights, chemical symbols, and atomic number. The arrangement of the periodic table leads us to visualise certain trends among atoms.
