Bromine has 7 electrons in it's outer shell. It can hold eight so, it needs 1 more electron.
The answer above is is probably the answer expected, however as the the question says outer shell which sometimes is used to refer to the highest principal quantum number, in bromines case 4, the answer could be 25, as the fourth shell can hold 32 electrons.
Anion (if it has an almost-filled outer shell) or a cation (if only the outer S orbital is filled or partially filled)
An element reacts with another element by sharing electrons. The elements keep sharing electrons until both elements have a full outer shell.
The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons, like the noble gases. Representative elements either gain or lose electrons to achieve this stable electron configuration, becoming ions with a charge that corresponds to the number of electrons gained or lost.
metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.

Yes, it is true. Until the inner shell is fully filled-electrons do not enter the next shell.

The atom's outermost electron shell determines its chemical properties and how it interacts with other atoms. It is involved in forming chemical bonds with other atoms to create molecules through sharing, gaining, or losing electrons. The number of electrons in the outermost shell also influences the atom's reactivity and stability.
Atoms share, gain, or lose electrons in order to achieve a stable configuration, usually a full valence shell. This is known as the octet rule. By doing so, atoms can attain lower energy levels and become more stable.
Magnesium chloride is an ionic compound. Magnesium has 2 valence electrons, and chlorine has 7. According to the octet rule, each element will bond in such a way that it ends up having 8 electrons in its outer shell--either by adding electrons to its outer shell until it has 8, or by losing all the electrons in its outer shell (that way, the next-largest electron shell--which is already full--becomes the new outer shell). Since magnesium has 2 valence electrons, it will lose two electrons (it's easier to go 2 - 2 = 0 than to go 2 + 6 = 8). Chlorine has 7, so it will gain an electron and have a full (8-electron) outer shell. There must therefore be two chlorines for every magnesium: each chlorine accepts one of the two electrons donated by magnesium. Magnesium forms two ionic bonds: one to each chloride ion.
YES! You crack the outer dark shell, and inside is the nutmeg that you will grate and use. But do not crack the outer shell until you are ready to use it. Out of the shell it will stay fresh for 2 years, but in the shell it stays fresh for 30 years!
The outer orbital, or valence shell, around the nucleus of an atom possess what are commonly called valence shell electrons. They represent the electrons available to share with another atom for the formation of covalent bonds between atoms. For Na, or sodium, in its standard atomic state there is only 1 valence shell electron. This number increases as you go to the right across the periodic table until the number of valence shell electrons reaches 8. This is noted by the Column number (i.e. I, II, III, etc.). Carbon has four, Nitrogen has five, Oxygen has 6, and Fluorine has 7. Xenon, Argon and the other 8th column elements are called the noble gases and they all have 8 valence electrons.
